Have no clue about Massachusetts, but I live in SoCal (close to their warehouse) and I get my parts within 2 days MAX. This is with rush order ($2.99) and standard shipping. It shouldn't take more than 3-4 days I'd think.
Newegg offers different shipping choices. You'll get your order in two days if its processed and shipped the same day. I just found out that they have another warehouse on the east coast, too.
There is no mandatory 2-day shipping rule...but they're fast.
It costs extra to have deliveries made on Saturdays, so most places like Newegg don't offer weekend deliveries. That's why you need to check their shipping policy.
It will more than likely arrive on Monday, Tuesday at the latest unless you pay for a faster shipping method.
