I can't answer any of your other questions but for Express I get popups when I use different browsers. It doesn't matter if I'm signed in or not. It usually pops up after you enter your zipcode when you're checking out. I haven't been able to get an approval though because after I click okay it sends me back to the checkout screen. Let me know if it works for you.
I just read about this shopping cart trick for the first time today. I'm rebuilding. My EQ is 660, I have proior BK (discharged in 05), and a few paid collections on my reports. I have about 12 inquires total, with 2-3 of those in the last 6 months. I'm an AU on 2 accounts that are 15+ years old, and have a few cards of my own that are all 6-9 months old. I have a Cap1 Secured (200), Kohls (400), Macys (800), Firestone (1000), Target (200) and I also have two Comenity cards (Ltd & NYC 750 ea.). Was just approved for Lowe's (300) today.
I have shopped on many Comenity retail sites like VS, J. Crew and Express for several years, including very recently, and have NEVER seen this pop-up! Wonder why it seem so readily available to some, and doesn't appear at all to others. I just tried a few today, and did not see any pre-approval pop-up. I want a VS card, but now that I know it's possible to get without a HP, I'm certainly not going to app for it. Grrrrrr.... so frustrating! Tips, anyone?
What browser did you use? I been using Chrome
I've used Chrome, Safari, Firefox, and even Explorer. I've gotten pop-ups for all of them. The problem is that Express has a glitch right now that'll keep sending the person back to the check out page. It's worked for me every time I try except when I try to do back to back. Also, I've found out that after you come back from using another browser it does the pop-up again. Pop-up works for both Mac and PC.
