I will say the lack of a buy box does have an effect. For example, I plan on listing bookshop, police station, and assembly square on amazon. Only Police Station has a buy box. The other two dont. Police Station is also going for about 100.00 over original retail, while the other two are around 35 to 40.00 over rrp. I'm sure the buy box makes a difference in amount of sales. I wish amazon wasn't ran like some third world country. Nothing they do ever makes any sense and there's never consistency.
