Pricing is definitely one of our challenges. We are currently paying prices of around 80% of what we think is a fair amazon market value, while giving the user a hassle-free sales experience. (Our prices are not manually entered but automatically calculated [e.g. based on price on Amazon, prices on other recommerce sites, ...]) This (almost) always leads to prices that are higher than Gazelle's or NextWorth's while also offering the convenience of getting paid within 24 hours.
