I occasionally shop in Ikea but I never enjoy the experience. It's very difficult to navigate, deliberately so. They want you to look at everything and unless you know the store really well you have to walk that serpentine dotted path to get out. I find it more than a little irritating.
And, after you've finally exited their maze, you get to assemble their furniture. That can be a delight.
I believe the IKEA in Elizabeth NJ, by Newark Airport, only charges 3.5% sales tax.
