How much will Cartridge World give me for my cartridges? -

I have some old cartridges and I saw a sign outside of the Cartridge World store that said they buy them. I can use some extra money(struggling full time student). How much will they give you for one.

$1 a piece if they are the ones they want . Generally you get less for generic ones that you can buy for $4.95 from re-ink companies. But if they are empty originals from HP or Canon they are worth more.
