I'd Rather Be At The Hideaway
Pretty sure it is just a deposit in case you don't return the clubs.There are some prices listed on the chart. Do you have to pay that amount for the product you want to test for 21 days?
Edit: From Bridgestone's site:
A temporary authorization hold will be placed on your credit card equal to the value of the shopping cart items and sales tax on those items.
This is the amount you will be charged for the clubs if you do not return them within the 21 day time limit as specified in the Terms and Conditions.
