I cannot help you with your question about a store, however, have you contacted the various companies and asked for samples?
I have gotten lots and lots of samples from Convatec, Coloplast, Hollister, Dansac, Cymed, and Marlen. I have even specifically asked for a product if I had read about it, like Eakin and Coloplast seals, specific appliances I wanted to try, etc. I have found the representatives to be very helpful and knowledgeable about their products. I have even heard that some reps are nurses, but have never specifically asked about that.
Convatec and Hollister both sent me nice little zippered canvas bag kits with scissors, mirrors, belts, etc--FREE.
I think Edgepark will send you a catalog with all the products they carry and there are tons of pictures and descriptions of the products. I wrote and highlighted all over mine with products I had tried and did or did not like and products others had recommended that I wanted to try. In many cases, these ended up being the free samples I asked for and received. The various companies also have their own catalogs.
In this link, Charles_in_TX gives lots of info on the various companies, along with toll-free phone numbers.
Someone routinely posts them on this board, but I could not readily find one of those posts.
