I am building a website for a nonprofit organization. I need to have a donate section on a page so people can donate as they wish using a credit card. The site is built with drupal, but I want to avoid using ubercart because of the complexity of it. Does anyone have any suggestions on what might be a good way to go with this? It doesn't need to be that fancy, just something that will take payments. The cost per month and fees is an important aspect as well. Thanks in advanced!
