It's been one week and two days since the sale. Judging by the enamorous amounts of people at just the one location that I was personally at, I can only imagine the ACTUAL amount of customers they received that day.
Having said that, they certainly did NOT get the orders all placed on Sunday, as most of their vendors/distributors were probably not available to place the orders. Moving to Monday, they surely had to get some, or most, of the orders placed at all of the vendors/distributors. So one week lead time from ordering on Monday would put you at Today - BEST CASE SCENARIO.
Realistically, chances are that all the special order items were not input completely until about Wednesday - would be my guess. And if each of those items had ZERO compatability issues (meaning: not back-stocked, not out-of-order, shipped timely, received timely, etc) - then you'll be LUCKY to get them by, say, Wednesday.
IMO - if you bought something cheap enough at the Sale, then you should be willing to wait a few days, period.
Cheap
Fast
Quality
...Pick two! So you got a quality part cheap... It's not going to get here overnight bud.
Just my observation on how things are probably panning out at Gearhead currently.
And, you're right that Gearhead does not have a Warehouse, but we've already pointed out the fact that SPW (Southern Performance Warehouse) is a separate business entity, and the items at said Warehouse were NOT included in the 50% off sale.
