This is ridiculous.
If as you say your amp was a "no brainer to sell," then sell it yourself. If you don't like their prices or conditions, then don't deal with them....simple.
TMR runs a well-managed business, they stay true to their business model, and the results of that model have allowed them to stay in business longer than most who play in the same arena. TMR has cultivated a client base by;
- Careful buying of gear/speakers that are in relatively good operational and cosmetic condition
- Internal inspection of the gear/speakers before putting items up for sale
- Relatively competitive prices for the age and condition of the gear/speakers they sell - not the lowest price you will find but in most cases well within the range
- Excellent packaging and shipping practices
- Stand behind the operational and cosmetic condition of sold items
- Offer a 30-day money back return policy (virtually unheard of in the used market!)
As stated previously by

If you don't like it, and aren't going to use it, send it back and we'll refund your money". 30 days after purchase. Their return policy is good as gold. You might pay a little more, but pretty much, satisfaction guaranteed.
I confirmed that return policy with them before purchasing a pair of $7K amplifiers, which I ultimately decided to keep.
