Anyone in the continental 48 Unites States may demo up to four racquets for six full days. The only cost to you is the shipping charges which are calculated based on your zip code. It's most economical to demo either two or four racquets. The racquets will be delivered by UPS within two days. You return them the following week on the same day of the week you received them. For example, if they arrive on a Monday, you ship them back the following Monday. Included in the racquet box is a postage-paid return label so all you have to do is seal the racquets back in the box, put the return label over the original label and take the box to a staffed UPS drop off center or any UPS driver. You can locate the drop off center nearest you using the UPS web page (be sure to select "staffed" for the drop off location type).
