I ordered an expensive pair of binoculars from OP. They were sold at a substantial discount, and arrived quickly.
Although the binoculars I'd ordered were very good, after trying them, I decided I preferred another brand which OP didn't carry. I contacted OP, and quickly received a return authorization and a prefilled UPS address label. The return was successful, and OP issued a complete refund, 5 days sooner than I expected. (They had 10 business days to issue the refund, but did it within 5).
I can't think of any way this transaction could have been more perfect, or demonstrated more integrity. Will I buy from them again? In a heartbeat!
