This is my second round of seeking reviewers. I am curious as to how AMZtracker sends out requests. Do all the same people get my second request who received my first request a few weeks ago when I had hundreds of responses within seconds unlike the 2 I've gotten for this round? I made the discounted price $1.95 because I learned from an experienced, successful Amazon seller that Amazon has been deleting reviews made by people who bought items for $1 while keeping reviews made by those who pay at least $1.95.
Secondly, I took AMZtracker's advice to state in the last bullet that I am offering tiered discounts. In order to avoid reviewers taking advantage of two great deals by checking unrestricted for combinality, I chose to check exclusive. Is there another way to ensure that the reviewers only purchase one of my items at such a huge discount? I know you suggest that we check unrestricted so that reviewers can buy from other sellers at the same time.
