Has anyone seen this bottle available for purchase in a store recently? http://www.coolgearinc.com/020bottle.html They are selling for $2.99 on the website, but shipping is $9, so I would rather purchase locally if I can. Last year I bought 2 of them at Walmart for $1.50 a piece. I haven't seen them in any Walmarts this year. If not, can you recommend a different inexpensive plastic water bottle with the freeze stick? Size doesn't matter really. These just worked amazing last year and I wanted to pick up a few more like it.
