MacSanta closing up shop

I am not sure if MacSanta ends at midnight Pacific Time or some other midnight, but I'm trying to get all my purchases done by 12 EST. One thing that is frustrating is that for a number of the apps there is not a clear way to use the discount. It doesn't always work in the coupon field and sometimes I've had to go through the process 3 times to get it right. Not to mention that not everyone takes PayPal and that sometimes if you use PayPal you can't use the coupon. Strange.
