I don't know how I did it, but I managed to score 7 Dior blush testers and a brush for $22.50 on Ebay. That's just a little more than 1/2 the price of a single blush. I've never gotten into dior blush too much because, honestly, they just don't perform like a $40 blush. If I were going to buy a blush in the $40-range then I'd get an Armani, Rock & Republic, 2 Laura Mercier or 2 Shu Uemura blushes.
These are very nice. They're exceptionally soft but also powdery. Be prepared for blush dust when you use these. They have a scent but I can't quite describe it. It's a sweet floral but it's subtle and you really have to stick your honker in there to smell it. My favorites of the bunch are Touch of Blush, Pinky Beige & Peachy Keen.
