Are you sure that buying another blender isn't common?
1. Maybe you didn't like it so returned it, but are still in the market.
2. Maybe it was a gift and you now want one yourself (or vice versa)
For something relatively expensive it may be the best expected value add even if the chance of repurchase is only 1%. Maybe the repurchase rate is 1% while the base purchase rate is 0.1%.
I'm not sure it is, but it seems entirely possible that this is actually a smart move by the ad engine.
