I try to keep my prices consistent across sales platforms. When I change prices on one venue, I typically try to change it everywhere. This doesn’t always happen though.
While at the ICA meeting, I sold an inventory-quality domain name. I went to check where the domain name resolved, and I saw it was resolving to a different platform. It also had a lower price by about $1,000. I was out for dinner, so I didn’t have a chance to either remove the listing or change the nameservers.
I thought if the buyer opted to visit the domain name before I had a chance to do something about the less expensive listing, he would might buy the domain name at the other platform for a lower price and try to get a refund for the first purchase.
Within an hour of receiving the sale email from the platform where it sold, I received a sale cancelation email. A short while later, I received a sale email from the other platform. The price inconsistency cost me more than $1,000. It was also a good lesson that I need to do a better job of managing my pricing.
On the flip side, this is one of the primary reasons I built DomDB.com: to help buyers find the cheapest place to buy any aftermarket domain.
It’s astounding how big the price differences can be for high-end domains (hah.com and two.com are a couple random examples).
Of course, there are automated seller tools for keeping prices consistent across platforms (DNX, Nerve.io, aftermarket.com?), but using them does involve some trust. I believe you must provide an API key for each platform to these tools, and if these API keys were hacked or leaked the results could be catastrophic.
