实施类似Groupon的系统有哪些选择？

Question

I like to build a system that will allow users to "commit buy" a deal, but will only be charged after a minimum # of committers are reached. The time span in which the "deal" will continue can be either weekly or monthly.

I like to stay away from building one from the ground up as much as possible.

I know there's another thread on StackOverflow that asked paypal, amazon, or google checkout API to serve this purpose, but this seems too much like a hack?

I did some reading on using a gateway like Authorize.net to process credit card information and they can store the user information and has a service like pay-as-you-go. Would using their API be a better choice? Can their pay-as-you-go method provide the system that I'm looking for?

I have used Authorize.net for recurring payments and it is easy to implement if you are fluent in working with a web service (regardless of language). You can integrate with them without the user needing to leave your website and without storing the user's credit card information.

However, you will be receiving the user's credit card number to implement such a model, and there are still precautions to be taken (versus redirecting to a secure third party site to receive the number).

Refine your question to be more specific to receive more specific answers.
