It's possible, I suppose. And other places would just follow suit.Not 100% sure but I'm almost positive that Wal-Mart required it due to lower shipping costs.
The weird thing is, they still carry Gillette Cool Wave in glass (one of the best glass aftershave bottles in current production too)
Definitely love the Gillette Cool Wave! My wife also loves the scent. If the scent came as a cologne, it's one I would purchase for daily wear. My preferred colognes for this time of year is John Varvatos and Burberry. The Cool Wave scent would be nice to have also though, especially in summer.
