Just received the pair of Columbia Mens Ultimate Roc Extended Pants. I liked what I received and immediately went on the Amazon web to purchase more and the price went from $14.90,(which I was charged) to $74.95!  The product tag states the MSRP is $70.00. This is very shady marketing by Amazon, don't like this kind of selling.
If a customer likes what he purchased, he should have the option to buy more at the same price. The website still had the $14.90 price but when I clicked to order, the price changed to $74.95.  Buyers beware of this company!
