Different prices based on size

[jimmmybe794]

I  received an e-bay e-mail that an item I am watching has had the price lowered.  When I go to the sellers' listing  the item is listed at the discount price but when I enter the size I need the price is not the sale price.  

It is posted as $7.99 but for my size it is $16.99.....that is more than double the sale price listed

Not very ethical......even department stores don't charge double for different shoes sizes
