shipping time is challenge with expercom. I compared both expercom and apple education store, and went with educational store. Apple shipping dates and return policy is much better. Luckily I am qualified for apple education discount. Good luck with restock fee with expercom.The best discounts are available at Expercom using discount code "appleinsider". Discounts on a $3,500 2020 iMac are just over $200. They also do not charge sales tax, which alone can reflect up to a 10% savings in some states. No sales tax plus another $200 in savings... what's not to like? I am not affiliated with them in any way, just sharing a good deal.
Expercom might work great, if you sure what Config you want and can wait for delivery time.
