After many years using Macsales and paypal, I was quite happy with both. Recently, however, I made a paypal purchase at MacSales. Turns out Macsale started using PAYPAL, but decided to cancel it, BEFORE ITS CURRENT TRANSACTIONS HAD CLEARED! I needed an exchange, and this ridiculous decidsion left me with no way to continue except to return for a refund. I learned a lesson: after discovering the hard way that MacSales "online help" is permanently "offline", and that their endless phone help cue is almost as worthless, I have reached the conclusion that Macsales is much less capable than paypal.
