Editable price for productos

[pymenweb]

Hi guys,
I just have made something weird with product prices in order to have a workaround to paypal donations at Mexico, where the service is very restricted  . Here is the scenario:

  +A member want to download a piece of software, we love if she/he makes a nice donation, anything of her free will, say $2, as in MX there isn't a direct donation solution, we set the price of the product to 1usd and we ask the user to change the quantity in order to reach his amount, say 2 x 1usd = 2 usd (obvious eh!), this way anyone can make "donations", no matter how many beers they want to bought us  because this mean send to the checkout process of paypal (as is) and not as a "donation" then accepted without complains here at Mex.

Now, here is the thing, it will very, very nice if we can set a product with a text box instead of price tag in order to allow the user to directly set the amount he wants to pay / donate for the product and process it "normaly" with a checkout PP button, can this be possible?

Thank you all for your comments!
