I've got several quilt magazine subscriptions that I'm going to let expire but that's one that I plan on keeping. I like the magazine. Everyone's opinions are different. What works for me may not work for you. With a deal like the one you have it takes the per issue price way down. Why not give it a try and decide for yourself.
My quilt subscriptions are one of the little treats I allow myself. Not every magazine is loaded with things I'll make by I look forward to getting them and they're relatively inexpensive compared to other indulgences I might have - shoes, jewelry, Starbucks every day, etc.
