i'd say try to log in every day to get the weekly coins + surprise bag at the end of the week! (also click this whenever you log in. its in every page on nav bar aside from Catch) also play spinami (under catch in the nav bar) bc you can get an item with a free spin. alot of the really good items (boxes, single items, etc) are behind gaia cash (bought with real currency) so i really wouldnt reccomend unless theres like an item or box you REALLY like. I will say, buyinig a cloud 9 membership will give you a free item on the first of every month. ALSO if you buy anything from marketplace, LOOK CLOSELY at prices bc A LOTTT of users overprice the FUCK out of items. you can also buy premade outfits on marketplace
also, i'm pretty sure when decorating profiles you can use css! oh also, items aren't completely colour tagged, so to get pink mostly items you'd have to input "cute", white is "pure", purple & green is "melty" so on & so on.
