En la etiqueta pone que la oferta termina mañana.

That is a very common question. In Spanish, especially with written text, poner can mean to say / to be written.

So:

• En la etiqueta pone... = On the label it says...
• ¿Qué pone aquí? = What does it say here?
• En el cartel pone que... = On the sign it says that...

This use is very natural in Spain. It refers to what is written somewhere, not to physically putting something somewhere.

Both can work, but they are not always used in exactly the same way.

• pone is very common for written information on labels, signs, notices, packaging, screens, etc.
• dice also means it says, but it often feels a bit more general and can refer to spoken or written language.

In this sentence, En la etiqueta pone... sounds very natural because we are talking about text printed on a label.

You could also hear:

• La etiqueta dice que la oferta termina mañana.

That is also correct, but pone is especially idiomatic when referring to what is written.

In this kind of sentence, pone is often used almost impersonally.

Literally, Spanish does not always spell out a subject here. The idea is something like:

• it says
• it is written

So in En la etiqueta pone que..., there is no clearly stated subject like the label. Spanish just uses pone in the third person singular to express the idea that the written text says something.

That is why it sounds natural even without a visible subject.

Yes, absolutely.

Both are natural:

• En la etiqueta pone que la oferta termina mañana.
• La etiqueta pone que la oferta termina mañana.

The difference is mainly in focus:

• En la etiqueta... emphasizes the location of the written information: on the label
• La etiqueta... treats the label more like the thing that contains the message

Both are common and correct.

En la etiqueta is the normal way to say on the label in this context.

Spanish often uses en where English uses on, especially for written information appearing on a surface.

Examples:

• En la caja pone... = On the box it says...
• En el menú pone... = On the menu it says...
• En la pantalla pone... = On the screen it says...

Using sobre here would not sound natural for this meaning.

Que introduces the content of what is written.

So:

• pone que... = it says that...

In the sentence:

• En la etiqueta pone que la oferta termina mañana

the part after que is the message written on the label:

• la oferta termina mañana

In English, that is often optional:

• It says that the offer ends tomorrow
• It says the offer ends tomorrow

In Spanish, que is normally required here.

Spanish often uses the present tense for future events when the context makes the time clear.

So:

• la oferta termina mañana literally looks like the offer ends tomorrow
• but it means a future event because mañana clearly places it in the future

This is very similar to English:

• The sale ends tomorrow
• My train leaves at 8
• We arrive next week

So the present tense here is completely normal.

Yes, you could.

• la oferta termina mañana
• la oferta terminará mañana

Both are correct.

The difference is mainly style and tone:

• termina mañana sounds more natural and everyday
• terminará mañana sounds a bit more explicitly future-oriented, sometimes slightly more formal or emphatic

In ordinary speech and writing, the present tense is often preferred for things like schedules, deadlines, and promotions.

Yes. These are possible alternatives, but they are not exactly identical in feel.

• la oferta termina mañana = neutral, straightforward
• la oferta se termina mañana = possible, but often less natural here
• la oferta se acaba mañana = very common and natural; often feels a bit more conversational

In many contexts, Spanish speakers would probably prefer:

• La oferta acaba mañana
• La oferta se acaba mañana

But termina mañana is perfectly correct and clear, especially in written or neutral language.

Spanish uses articles more often than English.

Here, la oferta refers to a specific offer or promotion that both speaker and listener can identify from the context, for example the offer mentioned on the label.

So Spanish normally says:

• la oferta termina mañana

not usually:

• oferta termina mañana

The version without the article would sound incomplete or unnatural here.

It can mean different but related things depending on context.

In a shopping context, oferta can refer to:

• a special offer
• a promotion
• a discounted price
• sometimes something close to sale

So in this sentence, la oferta termina mañana probably means:

• the special offer ends tomorrow
• the promotion ends tomorrow

It does not always mean exactly the same thing as English offer in every situation, so context matters.

Because here mañana means tomorrow, which is used as an adverb of time.

• mañana = tomorrow

Compare that with the noun:

• la mañana = the morning

So:

• termina mañana = it ends tomorrow
• termina por la mañana = it ends in the morning

The article changes the meaning.

Not in this sentence.

Without an article, mañana normally means tomorrow.

To mean morning, Spanish usually needs something like:

• la mañana
• por la mañana
• esta mañana

So termina mañana is understood as ends tomorrow, not ends in the morning.

Yes, that is also possible.

Compare:

• En la etiqueta pone que la oferta termina mañana.
• Pone en la etiqueta que la oferta termina mañana.

Both are grammatical, but the first one is usually more natural because it starts with the location of the written information, which is often what speakers want to highlight first.

Spanish word order is flexible, but not random. Different orders can slightly change emphasis.

Yes, especially the use of poner to mean to say / to be written is very typical and common in Spain.

Learners often first associate poner only with to put, but in Spain you will constantly hear things like:

• ¿Qué pone ahí?
• En el cartel pone...
• Aquí pone que no se puede fumar.

So this is a very useful real-life pattern to learn for Spanish from Spain.
