Hi - right re tradevegas.com mainly it's because it's short and easy to remember for the fence-sitters to type into their browser to look at the salesletter over and over again, before they finally succumb to my sales-pulling copy, whip out their credit cards and register their seat for the time limited discount they'll be able to take advantage of.
Good point though re grammatically it's not right, as you point out, Marcia - that's also my wife's feedback, she had suggest TradeInVegas.com or TradingInVegas.com , so I registered those, too. I'll have to split test response rates from these domains, I'll have them all resolve to the same end location, do a multi-variate split to my house list and see which gets clicked on the most... with the same exact email copy, except for the domain names, which will be the split test variable; I'll likely test 4 variants to see what pulls best.
Thanks for the feedback, all - makes sense.
Ken
