"Please, buy chocolate."

Translation: Пожалуйста, купи шоколад.

[brjaga]

Could you also use genitive here, like "buy some chocolate"?

[EfremSkopje]

That's a really old question but lemme answer that for new people wondering the answer. I'm nowhere near the mastery of russian but i think да, you can.

Пожалуйста, купи шоколада? should work

[JewishPolyglot]

Cool - in Hebrew it's also שוקולד/shokolad!

Ever notice the similarities between ш and ש?

[brjaga]

That's because they're both ultimately derived from the Phoenician letter shin. You might notice that they also look pretty similar to Arabic س and Greek Σ (albeit rotated).

It took me a while to realize this so I'll note it here
купи is the IMPERATIVE I believe
(don't try and look up the present or future tense of "to buy" or you will lose much time!)

[Momo_the_Avenger]

Can one say "Пожалуйста, купите шоколад" instead?

[Neon_Iceberg]

Yes, your choice is right. If it is not accepted, report it next time you will come across this task.

[ShelseaL]

What's the difference between купи and купите? like is one of them plural imperative?

[lizka654]

Купите is the plural imperative but could also be the formal singular.

[MateusViccari]

Yes and more:
Ты Купи - singular imperative informal
Вы купите - singular imperative formal, and plural

I know that "Купи шоколад пожалуйста" is also accepted but I keep wondering which one would be "used in a real scenario".

Can anyone, please, give some insight into which one would be more commonly used and why?
Thanks.

Can the perfective form, покупать, be used? So, 'покупай/покупайте шоколад, пожалуйста.'

[Kundoo]

"Покупать" is actually the imperfective verb. "Купи" is perfective. Yes, it's different from the usual pattern, but it happens.
