However some of the product you should go back to the retail stores are,
Big and heavy items -fridge, washing machines, (weigh in the handling and shipping cost)
Stuff with coupons -some retail giants offer huge discounts periodically to attract customers, if you shop a lot only coupons you might end up with a small profit too, as seen on TV.
Clothes and some designer items -usually if the stores has huge inventory build up they try to unload the inventory with massive discount, sometimes below their cost to cater space for new hot items or during season change. You can try it out physically and see whether the clothe suits you.

Generally buying something below the price of $20 range might still be wiser to do in stores, depending on what the online retailer charges for shipping and whether it collects sales tax. You have to be wise.
