I ordered a MAP sensor and power steering cap from www.wholesalemopar.com.
After 3 weeks of not receiving anything I emailed and they state they were waiting for the cap.
Well, I told them to send the MAP sensor and forget the cap. After another week I receive the airbox filter gauge (the resettable type). Contacted them and asked for a call tag since it was the wrong part, and they made a mistake, in the meantime I bought the MAP at local dealer since I couldn't wait anymore.
They refused to take it back unless I pay shipping, and they state it's the correct part and don't want to refund.
How stupid can they be not to know the difference from a MAP sensor to the part they sent ? And it's a dealership

Of course a chargeback from CC is in progress now.

What a bunch of crooks, I thought they were a decent place, but I was wrong obviously.
