shopping cart with donation capability?

[leppdesign]

i have been looking everywhere for a shopping cart online that accepts donations. my client wants to post mp3 songs on their site and have people pay for them by donation in the amount they choose. does anyone know of a software or system that allows for this?

Have you looked at this site?
Online Donation Services (http://www.itforcharities.co.uk/secure.htm)

Plus if I remember right if you use the shopping cart at this website below and you set the price to 0 then I think.....when I used it long ago.....that it let the customer pick the price.

the best bet would probably be to go to paypal.com (http://paypal.com/) and check out the various options and example in the developers section.
