In general (not this specific purchase): Often popular stock in sizes and models are too few, e.g. mystore running out of stock unless you manage to see the newest offers very early in the morning and quickly buy. After trying multiple times just to see a product being "sold out" every time (examples are big size clothes, shoes, popular sunglasses etc.) you end up giving up and ignoring future sales, ignoring mystore. Also, sometimes prices in mystore are actually not cheaper, even after the advertised discount is applied. My wife and I kept checking and comparing with standard shop prices, a bit for fun, and it seems the discount is sometimes taken from an substantially exaggerated price base, which makes me feel cheated, scammed. I don't know if that pricing comes from your sources or it is mystore that is responsible, but I would recommend not to do that - drives customers away fast. I would have given 5 stars if not for the two abovementioned reasons.
