How much do you want to pay?

I bought a tshirt for $2 in China after a long hard-fought haggle battle. It wasn’t worth it. I’m frustrated when I have to haggle for pricing.
So, how much do I want to pay? Would I be frustrated when I am given a choice? Usually people shop online for convenience and price. If my product is only sold in my online store, (ie- independent music) and the price is too high, I run the risk of losing the sale.

What if people could choose how much they pay ala a sliding scale?
