Lately new vendors have been offering florists "free" ecommerce websites for their flower stores. The problem of course is that they're not really free. True, the florist doesn't have to pay any fixed cost, but they do pay a much higher variable cost – 30% of every order that goes through the website goes to the website vendor.
It might not see like much but it gets very expensive very quickly. Even a florist that sells just one $40 order through their website each week will be paying more with one of these free websites.
"Free" is a powerful promise to make, but it is almost always misleading and this is no exception.
