I'm working on an online service right now. One of the most important assets I have is that I'll be introducing a mainstream service for a high quality and a significantly low price (lower than my competitors). I want to highlight this feature to attract small businesses and startups so I thought of integrating the word "cheap" in the service's domain name. Is it a bad decision?
Do you ultimately want to be perceived as "Walmart" or "Nordstrom"? If what you're emphasizing is low price, then that's who you'll attract and that's what you'll be competing on.
Raising prices in the future would be very difficult as well.
It would be more satisfying, (and your margins will be higher) if you stress the value they would achieve by using the service.
