Advertised products

You know how you always get junkmail in your postbox. I don't usually read them but some baby products special caught my eye. I went to the shop and there was none of the advertised products. I went the same day as the special started and nada, nothing!

I simply hate false promises. In the end I had to pay much more for the product cause it is just too much driving around town trying another shop.

Shouldn't shops keep stock of things they advertise?
