Thanks! Just picked up two things that looked interesting enough to try, but not quite enough so that I'd have likely bought them on my own, so the choose-your-own-freebie offer is much appreciated.
Also, I notice they have a
Fantastic Megapack Bundle™ which gathers together 22 of their assorted mostly-sfnal megapacks for just $20.00, which looks like it might be a good purchase with the 50% off holiday coupon offer on top of the $2 off the individual price.
