Depending on the town / city you live in, you might try someplace like Dillard's, Macy's, Younkers. Some of the more upscale department stores I believe would have more choices to offer you than Wal-Mart. In addition, I believe the clerks are more helpful and knowledgeable about their products.
I don't know how you feel about online shopping, however, use your department store to get measured and to try on several sizes. Once you decide on which bra would work best for you, you can go online and search for that style, pattern and size to see if you could get it cheaper there, or just take the plunge (ha ha) and buy it there. Hope this helps.
