Ich brauche heute kein Toilettenpapier mehr zu kaufen; ich habe gestern in der Drogerie gleich zwei Packungen mitgenommen.

Because kein is the normal way to negate a noun when English would say no or not any.

• kein Toilettenpapier = no toilet paper / not any toilet paper
• nicht usually negates verbs, adjectives, adverbs, or a whole statement

So here German treats Toilettenpapier as the thing that is absent, and kein is the natural choice.

Also, Toilettenpapier is a neuter singular noun, and in the accusative singular kein has the form kein, so the phrase looks exactly like this.

In this sentence, mehr means any more / anymore / no longer.

So:

• kein Toilettenpapier mehr kaufen = to buy no more toilet paper / not buy any more toilet paper
• Ich brauche ... nicht mehr ... often means I no longer need to ...

Here the idea is that the speaker has already taken care of the toilet-paper problem, so there is no need to buy any more today.

This is because of the construction brauchen + zu + infinitive.

German often says:

• Ich brauche das nicht zu machen.
• Du brauchst kein Brot zu kaufen.

The conjugated verb (brauche) goes in the usual second position in a main clause, and the infinitive phrase (zu kaufen) goes to the end.

So the structure is:

• Ich brauche ... zu kaufen

That is why kaufen appears at the end.

In standard German, brauchen used in the sense of need to usually takes zu:

• Ich brauche nicht zu gehen.
• Du brauchst das nicht zu kaufen.

In everyday spoken German, many people omit zu, especially after nicht:

• Ich brauche nicht gehen.

That is common in speech, but with zu is the safer standard form to learn and use, especially in writing. So Ich brauche heute kein Toilettenpapier mehr zu kaufen is fully standard.

Because Toilettenpapier is usually treated as an uncountable material noun, like paper in English.

You normally do not count it directly as separate items. Instead, you count units such as:

• eine Packung Toilettenpapier = a pack of toilet paper
• zwei Rollen Toilettenpapier = two rolls of toilet paper

So in the first clause, kein Toilettenpapier means no toilet paper / any toilet paper, not no toilet papers.

Because Packungen is the counted unit.

Since Toilettenpapier is usually uncountable, German often counts the packaging or portions instead:

• zwei Packungen = two packs
• drei Rollen = three rolls

So the sentence does not count Toilettenpapier directly; it counts Packungen.

Grammatically, zwei Packungen is the direct object of mitgenommen, so it is in the accusative plural.

Here gleich adds emphasis. It means something like:

• as many as two
• a full two
• two right away

So gleich zwei Packungen suggests that the speaker bought not just one pack, but two, perhaps to make sure there would be enough.

This use of gleich is very common in spoken German for emphasis.

Because this phrase describes location, not movement toward a destination.

The preposition in is a two-way preposition:

• dative for location: in der Drogerie = in/at the drugstore
• accusative for direction: in die Drogerie = into the drugstore

Here the sentence means the speaker was at the drugstore when this happened, so German uses the dative: in der Drogerie.

Mitnehmen literally means to take along / take with you. In shopping contexts, it often naturally means to pick something up and take it home, so it can strongly imply that the person bought it.

So:

• ich habe zwei Packungen gekauft = I bought two packs
• ich habe zwei Packungen mitgenommen = I took two packs with me / I picked up two packs

In context, mitgenommen sounds very natural and everyday. It focuses a little more on the act of taking them along from the store, not just the purchase itself.

Mitnehmen is a separable verb.

Its basic form is:

• mitnehmen = to take along

In a normal present-tense main clause, it splits:

• Ich nehme zwei Packungen mit.

But in the perfect tense, the prefix stays attached to the past participle:

• Ich habe zwei Packungen mitgenommen.

So mitgenommen is the participle of mitnehmen.

Because in everyday German, especially in speech, the Perfekt is the usual way to talk about completed past actions.

So a speaker will very naturally say:

• Ich habe gestern ... mitgenommen.

The simple past is also correct:

• Ich nahm gestern ... mit.

But that often sounds more literary, narrative, or formal for a verb like mitnehmen. For normal conversation, habe ... mitgenommen is much more common.

German word order with time, manner, and place is flexible, but a very common pattern is:

• time before place

So:

• gestern in der Drogerie = yesterday at the drugstore

That is why gestern comes first here. But other orders are possible for emphasis, such as:

• Ich habe in der Drogerie gestern gleich zwei Packungen mitgenommen.

That version is grammatical too, but the original order sounds more neutral and natural.

The semicolon links two complete main clauses that are closely connected in meaning.

Here the second clause explains the first:

• I do not need to buy any more toilet paper today;
• I already picked up two packs yesterday.

A full stop would also work:

• Ich brauche heute kein Toilettenpapier mehr zu kaufen. Ich habe gestern ...

A comma alone would not normally be correct here, because these are two independent clauses without a coordinating conjunction such as denn or und.
