Another bride mentioned you can check online to see if they are in stock, this didn't work for me in the area I was but I am not sure why.
When I got mine they were in the seasonal dishware section so with all the outdoor plastic dishes, trays and glassware. It would have been really easy to pass them by since they are bright colours. Also they were at the end of aisles around the other insulated mugs. Maybe try calling a few walmarts around you, maybe they could tell you if they have them?!
