Most people want to know what they're getting for the money spent, without hype. A list of benefits usually works well, without exclamation points, if possible. Talking about saving money and saving time are just as important as earning money.
When selling high-priced items, tell people how little it costs DAILY, such as..."You get all this for ONLY 54 cents per day." That works well for me.
Also let paying customers know if they can earn back their investment by selling, such as..."Sell 2 and your cost will be covered, then it's all basically FREE for you after that."
Also try to get customers to purchase a yearly membership instead of monthly, so they'll probably save money that way and you'll earn a bigger commission upfront. You could say "You save $xx.xx by purchasing yearly." ...or..."Getting the yearly membership is like getting 3 months free." Put it in a way that really drives home the amount of savings for a yearly membership.
