It was problematic, because, after buying the product online, I received an e-mail asking me to complete the transaction. The link I was given took me to your general home page, so I reordered the product. Later I happened to be looking at my credit card statement and saw that I had been charged twice.
To make matters worse, the second order was related to an e-mail address that I never normally use. I have no idea why.
I had to pay the costs of returning the duplicate pair of shoes.
