I tried them out, but for me, the system is very tough, if not impossible, to use.
For example, there is really no functionality to enforce a "Minimum Bid" limit, and what happens is that any bid from $1 up is allowed (you can even leave the offer field blank), but sellers only get notified of those offers that are at or above your stated Minimum Bid.
So what happened to me is that I never got a single email stating there was an offer, but when I went to the NP listing area, there were tons of low-ball $10 and $20 offers all over the place. Naturally, I was not pleased so I asked NP why this was happening when I had entered a Minimum Bid and was given the explanation I outlined above. Essentially it's an entirely open system for bids of any amount, and your Minimum Bid is just a notification setting. Great.
So without any enforcement on your Minimum Bid, the NP system really doesn't work for me, and your NP domain dashboard can quickly turn into a huge mass of hobos and lowballers spamming you with $10 and $20 non-offers. You also can't delete these offers either, and I can't even imagine how incredibly messy it would get in a year's time. And I can imagine quite a bit.
