i have 300 coins. what to do?

i have 300 coins and am curious if anyone has any suggestions on what i should spend on for poe2.

I'm changing this post because I noticed the sale is still going on (buy today). This is what I would buy with 300 coins...

A Premium Stash Tab Bundle (165)
A Currency Stash Tab (60)
A Gem Stash Tab (30)
An Upgrade to Premium Stash Tab x4 (40)

This route will absolutely give you the best bang for your buck (assuming you want to do trading/selling now or in the future).
