[Question] List of items to buy with gold before stockpiling Mats?

Hello,

So i'm new to the 20 scene with a F2P account. I was curious if there is a list out there of items you can buy with gold that would either help your character, or help you get rid of gold before you begin to stockpile mats to save your gold? (The flask I think is the best?) Since we don't have access to the Warbank deposit. Or if we do my game is glitched and doesn't let me haha.

Items I'm referring to can be anything from the mounts, pets toys etc. I spent my gold so far on all toys from Dalaran Vendor, pets I can find in Dalaran too, all mounts (before getting reputations for the others so working on that) the sunglasses by the Vendor in Org/SW. I purchased all bank slots/void storage. So I'm just kinda lost on what to spend the gold on next before stockpiling it in the potions/mats.

Again, newer to this so any help much appreciated. Thank you.

just pick a item or two, stack those. or use the gold buy old gear for tmogs and DE. so far i have blown way over 22K gold using two players
BC gear in shattrah, there are several vendors
CATA gear in ORG/SW
WOTLK gear in northrend dalaran

select ALL at vendor so you buy gear for other classes once you run our of gear for your class
