Debra, thanks for the link to the discount site.
Whatever shoes you get (and I'd suggest going cheap at first, as your wear patterns will be strange as your gait changes), I'd recommend regularly going back to 'true barefoot' at first: this is the only way you will get the feedback you need, as whenever you have the form wrong, it will feel bad.
Once you have settled on a form, you might not be as comfortable in shoes with a supported heel, but you can still transfer the forefoot style to most shoes.
Don't be afraid of landing on the heel as well as the front-foot. In my opinion, this uses the foot's mechanics in a perfectly natural way, and you're far less likely to get a stress fracture. I've never had any plantar issues from using midfoot rather than exclusively forefoot. If you do use true forefoot, you don't want to be too far forwards so that you're onto your toes.
