Understand your frustration but Adorama technically hasn't done anything wrong, it just seems like bad timing. I realize that most major retailers now have a price match guarantee or honour sale prices within a certain window.
But... is the lens you bought available at those stores?
You are probably right where technically they didn't do anything wrong. However, telling me to return somethign for the same thing isn't a good answer at all (that's my opinion)...
I get it, i missed the special deal on Twitter, The VISA deal i sfustrating becuase it happen a bit over 2 hours after i ordered.. And today's deal is also fustrating becasue I want to keep the lens - not send it back and re-order.
Anyway -- i will drop it..
