2.00, maybe 3.00 depending on the content and quality.
When you sell buttons, you're usually going to sell them in bulk because people are going to want to collect them all, so keep that in mind with pricing.
One suggestion I have is to sell them in slightly discounted sets too. If you buy the full set it's a little cheaper than if you buy each button individually? =3 That way people will be encouraged to buy more of them.
hey you butt I have learned from past experience that you'll actually sell MORE of something if it's an even dollar than if it has change (ie $3 sells better than $2.50) i'd sell them for $3 two for $5 fuck da popo
