Deceptive eBay marketing tactic?

[Bram99]

I see the same emails as you mention. Here's what I think is happening. I might look at a card like an Allie Reynolds 1949 Bowman in NM-MT PSA 8. Let's say it's $150. Then I get an email that I can save 80%, but when I click through, the card they are referring me to is not an 8 but rather a 2.5 or even ungraded. I don't know that it is deceptive - it's more annoying than anything. I think their algorithms can't account for the specificity of details in a listing and probably just search for 1949 Bowman Reynolds in the case, and show me something way different in condition / grade that what I was looking at.
