Review on Strength Black Nylon Bolt Dropper by Randy Albright

I ordered 1000 11" cable ties and they arrived and were perfect. I also ordered these 8" zip ties, they are thinner and won't fit 11" zip ties when I need to make them longer. Why other sizes? Now I want to return them but Revain sent them via UPS. In Puerto Rico there is only one UPS store and that is an hour away at the airport. To send them back with USPS I would have to pay for the shipping myself which is about the same as the cost of ties and there aren't any for that Guarantee I will ever get a refund I am not satisfied with Revain Why can't I use USPS or UPS?
