d4 player here... just bought $480 wraeclast pack

i have 4800 coins.. what do i spend on?... this pack i got 5 poe 2 early access keys and is everything for poe 2 right? i didnt just spend $503 after tax and shipping for poe 1 stuff did i??

It's for both poe1 and poe2. Some weapon skins might be exclusive to poe2, since they are not present in vanilla.

Question out of curiosity - why do you feel the need to let people know that you're a d4 player? Is it some kind of a universal sign of impairment, or what am I missing?

Stash tabs are best initial investment.
Wait for the next sale, it is every 3 weeks except at league launch (that is delayed a week)

Maps
Currency
Essences
Divination Cards
and quad tabs.

These are the ones I feel are, sort of, a minimum for good inventory management. (personally my favs, ymmv)

even if you have a lot of points it is recommended to wait for special offers
unless money isn't a problem for you

Buy one stash tab of each (Currency, Maps, Fragments, Essences, etc), 4 x "Upgrade to Premium Stash Tab", for the initial tabs you got when created the account, and a few quads for storage. Don't buy more then one "Premium Stash Bundle", because you wont be able to upgrade those tabs to quads. A single Premium Stash Bundle is good for pricing items in bulk (eg. a tab with 20c items, one for 40c, etc).

You should wait until stash tabs are on sale, you'll be able to save a lot of points. Usually they are on sale for a weekend per month or so, and the weekend after league start. They might be on sale in the PoE2 EA weekend, 6-8 December.

Welcome to the world of good content!:)

About your question: as people answers before. Get the stash tabs first. These are very helpful to organize your storage.

As everyone else has said, stash tabs. Quad tabs are nice, but they also are less cost to space effective than a standard stash tab (at the bundle price). You will want all tabs to be premium at a minimum.

For regular MTX just enjoy what you have for now and branch out when you want something new or see something you like. You can always select to receive a notification whenever a specific MTX goes on sale.

I'd also save points for PoE 2 and see if any new specialty tabs are released then.

Im on PSN and I can't find anywhere to buy the supporter pack for a key. If they make us wait until Dec 6th thats so lame of PSN

As a general rule, you should buy:

Currency Tab
Fragment Tab
Map Tab
Divination Tab
Essence Tab
At least 2 quad tabs (These are great for finishing a map, dropping off items, and moving on to the next map to maximize time)
And a few special tabs for selling items
Gem and flask tabs are nice to have.
To start, this is enough. Later, you can buy skill skins you like or more tabs; it's up to you. And if you have an extra key for PoE 2, you could send it to me :)
