What payment gateways do you use for your app?
huhtenberg: > Since Authorize.Net require you to have a merchant account in US, we, Canadians, can't use it.Actually we can. The do however require that you open an account with Global Payments Inc and these guys have seriously sleazy sales tactics. They break down their fees into a multitude of categories and groups, and it is fairly unobvious what combination of these fees you are going to hit most frequently. It took me literally a week of back and forth emails with them to get an idea of what the average transaction fee would look like. It was really like pulling a tooth.I have also dealt with Moneris. Extremely arrogant. They are really big and they basically do not care. They are also the most expensive of all that I have talked to.Lastly I spoke with VersaPay and they first quoted me fees that were frankly exorbitant. Only after I told them the Global Payments fee level, they brought theirs to the comparable level.In the end I haven't gone through with any of these, but if I were to pick one now I would probably give VP a try.YMMV, etc.
