Yep, I get EXP pulls for every Citi, Chase, and Amex card. But Citi decides to be extra special, and also pull EQ for every single card. Chase pulls EQ for half of them - I'm thinking it's the business cards. As others have said, Barclays is the only one that pulls TU.
For those who have tried freezing EXP for Citi, were they also pulling EQ for you? I'm wondering if they would be satisfied with just pulling one bureau.
In other news, it sounds like EXP must be running a sale on credit checks, if you buy in bulk. Pre-pay for 100k, and the next 100k are half price.
