Best price found by Price Grabber was $107 shipped in the US. Pricing strategies are very complicated. A manufacturer targets an overall margin % and the margin % of individual products varies. The margin on the N810 will be lower to attract buyers and the accessory margin will be higher to on average bring the average up. Someone that only manufactures accessories may well have a lower margin because they aren't making up for lower margins on some of their products. Cost to manufacture is a factor but the market's willingness to pay determines price. The Nokia brand has an image that makes that willingness price higher. I purchased the SU-8W for the perceived quality and assumption that it would work well with N810. If your buying priority is price 1st you would make different decision than I did.
