Best Deals
Tophatter's makes every effort to have the lowest price on the internet for daily deals on the day they are offered for sale. This means that you will not find a lower price anywhere from a valid seller with an identical product. It is possible, on occasion, that you may find a lower price for the same thing on an eBay listing, but they are often used and we can't gauge the quality of the company or their service, so we don't even try to compare our product prices to them. We often list the "Retail Price" of an item for comparison purposes. This is typically the Manufacturer's Suggested Retail Price or MSRP. Products are sold below MSRP in many instances, especially watches and jewelry. On the other hand, many of the top brands often don't allow any discounting from MSRP by their retailers except in special situations. Tophatter's does not attempt to portray the "Street Value" of an item. The street value fluctuates too much to effectively follow and there is no standard on which to base this price. You can get estimates of the price an item typically sells for elsewhere, on sites like Google Shopping or Amazon.com. Most of the time, however, Tophatter's will have the best price, and usually by a generous margin.
