I'm looking to buy a shengshou 8x8, 9x9, or 10x10. White or black, doesn't really matter. I like bright shades, but if the stock shades are on there that's fine. Please, not too expensive, either, use your discretion.
Yeah, usually for bigger cubes the retail prices go up exponentially, but usually some people would be willing to sell theirs for less than retail. I could get a 7x7 for less than 20 dollars here, and then to buy the next size up (for retail price), the price goes up 2.5x.
