Not true, an account I used to sell BH products had 1 iTrader and was only around 1 month old with under 30 post's, I gave 0 review copies and still made around 8 sales for a $7 product. Nothing to write home about but still some cash for about 10 minutes of work, I used the money to buy cigarettes.
Had I priced the product over $10 I probably would not have made that many sales, DP forum rats love to get the world for under $10, so it's your job to bottle the world up and stick a price tag for it under $10 and yo'll make sales.
