The TINSEL RAIN (sequel to FROZEN DREAMS: buy it now!) won’t be happening until March, but I’m working on setting it up now. My question is: I plan to offer signed copies of my other books as incentives. Should I do them as add-ons, or different tiers? The advantage of tiers is, I can combine shipping and handling costs; the advantage of add-ons is, it’ll make for a cleaner display. I’m not wedded to either tactic, so opinions welcome.
