I know it doesn t help, but the only place I know was on S Colorado Blvd and closed years ago. You might try Bake Mark. I think they are wholesale but might also sell retail. http://www.bakemark.comYou might also call some of the gourmet specialty stores and post this question on Chowhound.
Did you try looking for craft stores? Cause, you know...Michael s is a craft store, but, as you have noticed, very corporate, and they have the brands that their company buys for them....but a smaller such shop might have access to other things, things they could order specially for you, stuff like that. I guess Walmart wouldn t make you any happier...pretty much the same stuff as Michael s, but less of it...our little tiny Walmart has a few things, but a super store might have a better selection.
