AVOID!! Seller added reserve price AFTER I won the auction because was not happy my final winning bid of $5.
Rules:
6.2.2. Reserve prices for auctions are not permitted; auction holders (sellers) must set a starting bid that they are prepared to accept.
For a first time buyer and new to NP, I would say they did very well. If the continue to communicate well and be prompt with payment, they will gain a solid reputation among domain sellers.
