Hi, i tried to purchase on http://www.askmebazaar.com a few days before and there was an offer "daily jackpot", i was not able to buy with size 10. whenever i click buy now with size 10 pre selected. it shows size 6 in cart list. Today i tried again to purchase a shoe with size, now iam able to add the product with size 10 to my cart and i got 50% off in "daily jackpot" but i just can t checkout the item, the page keeps refreshing when i submit the shipping details . once it get refreshed it automatically remove my offer price the shows original price.then i applied my coupon code and now it shows price as 0. anyway i submitted it and same page again refreshed.. what an irritating system, iam sure i know the process of buying. i have purchased from the same site before and have lot experience from other sites too.
