Amazon has different kinds of coupons. They have classic coupons that you have to type in the shopping cart, but they also have CLIP-ON COUPONS. You don’t have to type these, you simply click to virtually clip the coupons. This adds the coupon to your Amazon account, so if or when you buy an eligible product, while the coupon promotion is running, you will automatically get the discount.
One of the items that currently has a clip-on coupon is the Dolica GX650B204 Proline GX Series 65 inch Aluminum Tripod and Ball Head Combo. It goes for the very specific price of $62.55. After the $5 off clip-on coupon, it drops to $57.55 with free shipping.
The tripod goes for $55 at Adorama, however, Adorama has mandatory shipping that starts at $9~, so unless you have a way to get free shipping at Adorama, the total price is higher.
