My advice: just have one high priced bucket.
Then you will filter out bargain hunters -- they require at least as much support [1] -- and focus on price insensitive customers (they are the most profitable). Price insensitive customers also provide a clear indication of what people will willing pay for (people who want free don't want to pay for anything so there is no clear signal).
Your job is to solve your customers' problems. Except for how much your product costs.
[1]: Notice that you already have a complaint from a non-customer. You don't want customers who want you to solve that problem.
