Also not a fan of eBay, but recently picked up my 10.5” 64gb for $351 tax free. Coupled with my purchase of the Smart Keyboard for $61 and Apple Pencil at $49. Total is $461 out the door, granted that is with the 20% off coupon ebay had a few weeks back. For the price, undoubtedly the best iPad I have owned, which has been most of them, just no longer willing to pay full retail as deals pop up much more if you are patient.
I wonder why the LTE iPads also aren't under a steep discount. Maybe after WWDC, but having the option to use LTE data is nice (I use a prepaid plan for data on my iPad)
