I don't think qhemet will be open on thanksgiving, so go with Sage.
As for Curl Junkie, I believe they are gonna be offering the same discount as AveYou and unless you're ordering $100 worth of Curl Junkie, AveYou will have a better deal on shipping. (AveYou's shipping policy is: $5 shipping for orders under $50. $1 shipping for orders over $50.) Plus you'd be able to order other stuff besides Curl Junkie if you wanted.
The better deal goes to AveYou, IMO.
