Add some new filters/options to the advanced marketplace search option, such as:
Checkboxes for gigas, coins, and botstract offers (so you could search for only giga offers, or giga + coin offers, etc). Would be nice when browsing for snowballs, trans coupons, etc.
Price ranges, so you could enter a min/max price and only see offers in that range
Also make it so that you can search for v1/v2/v3, reapers, and S/P/R efs (I can't search for any of these, but that may just be me doing smth wrong)
