Though not confirmed on all counts, it looks like Apple’s iPad 2 will be available from several third-party retailers at launch. Best Buy, the nation’s largest consumer electronics retailer, has already confirmed that it will carry Apple’s second-generation iOS tablet starting March 11th, as was expected. 9to5 Mac now reports that in addition to Best Buy, nationwide retail giants Walmart and Sam’s Club will both carry the iPad 2 at launch as well. Both chains already have iPad 2 SKU numbers showing in their respective inventory systems, the blog’s source claims. The report might help quell rumors of potential launch inventory shortages that have been swirling for the past month.

UPDATE: Walmart just made it official — and it will offer each model for $1 under MSRP.
