I've never had a good experience using the Walmart website. Shipping has always been slow and that's only if they actually have what I want in stock. In general, it's always been frustration.
One star off for fake members (though they are everywhere), but if you are not blind, you can easily distinguish them from the real ones.
But overall - I really enjoy my membership on the site. I've had few hot dates and I'm not going to stop!
