The best advice I can give you is to take it slow with collecting. Collect what you like but don't go overboard.
This is an expensive hobby and, IMO, you need to choose what you buy carefully or you'll go bankrupt!
Long gone are the days when 1/4 statues and 1/6 figures cost $150 or $50 respectively. Even 1/12 figures run about $25 bucks nowadays.
But idk who I can go for help with knowing what the going rate is for the figures. I don’t want people to take advantage of me and idk how to sell them on eBay.
