It seems that Angel: The Curse keeps selling out. IDW has gone to a third printing of #1, and I've heard rumors that #2 is sold out as well. I also occasionally hear from people who are having a hard time finding copies.
With that in mind, I've asked comics retailers to let me know if they have stock, so I can let you know. I have heard from a few, and as I hear from others I'll pass the word along. For the moment, I KNOW these shops have copies:
1A Bellevue Park Plaza
Belleville, IL 62226
Famous Faces & Funnies
3146 Lake Washington Road
Melbourne, FL 32934
Redd Skull Comics & Cd's
720A Edmonton Trail North East
Calgary, Alberta Canada T2E 3J4
If they're not in your neighborhood, they might ship there. You can also try IDW directly at IDW.
