Too many duplicates!!

Ive been playing this game for a while now and its not the greatest game but it is pretty fun. I used to get duplicates, rare, whatever the other sticker(s) are called, but now Im getting only duplicates! Its very annoying! I know that you can trade with someone through Facebook accounts but I dont have a Facebook account so I cant trade {:( if you dont mind, then please make it so that you can get the other stickers a little more often {:)
