A big comercial on mlsnet.com about MLS merchandise in Walmart stores, I went (rt. 46 in Saddle Brook) and they have nothing, it's just incredible how dificult it is to find anything MLS related besides online stores.
Did you bother actually clicking the link or did you just read the banner? It says very clearly what stores would be carrying the merchandise, and none of them are in the tristate area. http://www.mlsnet.com/gear/walmart.html
Interesting spot for a Walmart.... 1401 South Cherry Lane White Settlement then again, I used to live in a state with town names as Intercourse, and Blue ball......
