Продавщица проверила наличие ещё раз и сказала, что товар уже везут со склада.

Продавщица means saleswoman / female shop assistant, while продавец is salesman or sometimes a gender-neutral salesperson depending on context.

In this sentence, проверила and сказала are feminine past-tense forms, so the subject must be feminine. That is why продавщица fits naturally.

• продавщица проверила = the saleswoman checked
• продавец проверил = the salesman / salesperson checked

Проверила is the perfective past form of проверить, so it presents the action as a completed whole: she checked once and finished checking.

Проверяла would be imperfective and would suggest:

• a process,
• repeated checking,
• or emphasis on the activity rather than the completed result.

Here the sentence moves the story forward in a sequence:

1. she checked,
2. then she said something.

So проверила is the natural choice.

Наличие literally means presence or availability, but in shop/business language it usually means whether something is in stock / available.

So проверить наличие is a very common expression meaning:

• to check availability
• to check whether an item is in stock

It sounds a bit more formal or business-like than a very everyday phrase such as посмотреть, есть ли товар.

Because наличие can stand on its own when the object is understood from context.

Earlier or elsewhere, the speaker and listener already know which product they are talking about, so проверила наличие means roughly:

• checked availability
• checked whether it was in stock

Russian often leaves out words that are obvious from context. A fuller version could be:

• проверила наличие товара
• проверила наличие этого товара

But in natural speech, that is often shortened.

Ещё раз means once again / one more time.

So проверила наличие ещё раз means she checked the availability again.

A useful point:

• ещё on its own can mean still, yet, or more
• ещё раз is a fixed expression meaning again / one more time

Examples:

• Скажите ещё раз. = Say it again.
• Я ещё не знаю. = I still don’t know.

The comma before и сказала is there because the sentence has two past-tense verbs with the same subject in a longer structure, and Russian punctuation often separates such coordinated parts more readily than English learners might expect in longer sentences.

The comma before что is very important: что introduces a subordinate clause:

• сказала, что... = said that...

So the structure is:

• Продавщица проверила наличие ещё раз
• и сказала, что товар уже везут со склада.

That last part is a clause dependent on сказала.

Товар is often used in Russian as a general word meaning:

• item
• product
• goods

In this context it usually refers to the particular item being discussed, so singular is natural: the item/product is being brought.

Even though English might sometimes prefer something like your order or the goods, Russian often uses товар very naturally in shop and delivery contexts.

Везут is 3rd person plural of везти: they are bringing / transporting.

But here it does not necessarily mean a specific known they. Russian often uses 3rd person plural to express an indefinite agent, like:

• they’re bringing it
• it’s being brought

This is very common when the speaker does not need to say exactly who is doing it:

• warehouse staff,
• delivery workers,
• couriers,
• etc.

So товар уже везут со склада means:

• they’re already bringing the item from the warehouse
• or more naturally in English, the item is already on its way from the warehouse

Because Russian present tense is exactly what you use for an action currently in progress.

Везут here means:

• are bringing
• are transporting
• are on the way with it

So this is a normal present-time ongoing action.

Also, везти is the correct verb when something is being transported by vehicle or carried along in transit.

Compare:

• нести = carry on foot / in one’s hands
• везти = transport, bring by vehicle

This is mainly an aspect difference.

• везут = imperfective, focusing on the process: they are bringing it
• привезут = perfective future, focusing on completion: they will bring it / they will have it delivered

The sentence means the item is already in transit, so the ongoing process matters. That is why везут works well.

If you said товар привезут со склада, that would usually mean:

• they will bring the item from the warehouse with more emphasis on the future result, not the current movement.

Russian normally uses с / со + genitive with склад in this kind of meaning:

• со склада = from the warehouse

The form со is just a pronunciation variant of с, used to make the phrase easier to say before certain consonant combinations.

So:

• с работы = from work
• со склада = from the warehouse

Из склада is not the normal expression here. With склад, Russian idiom strongly prefers со склада in logistics and stock contexts.

Склада is genitive singular.

That is because the preposition с / со meaning from requires the genitive case.

Base form:

• склад = warehouse

After со:

• со склада = from the warehouse

Уже means already.

It tells you that the situation has progressed further than expected or than before:

• not just they will bring it
• but they are already bringing it

So the sentence suggests reassuring news: the item is no longer merely being checked or requested; the delivery process has started.

Russian word order is flexible, but the original order sounds natural and clear.

Продавщица проверила наличие ещё раз и сказала, что товар уже везут со склада flows like this:

1. who acted,
2. what she did,
3. what she said,
4. the content of what she said.

You could change parts for emphasis, for example:

• Продавщица ещё раз проверила наличие...
• ...что со склада уже везут товар.

But the original version is the most neutral and natural for ordinary narration.

Yes. Several parts are very typical of service/shop Russian:

• проверить наличие = check stock/availability
• товар = item/product
• везут со склада = it’s being brought from the warehouse

So the sentence sounds like something a shop assistant would really say in a store when an item is not immediately on hand but is being sent from storage. It is formal enough for customer service, but still completely natural.
