Apparently there is none, till now
There are 3 flavors to dell:
The average Joe can shop in any of them and the prices/configurations will vary between all three. Take the time to look in all three to find the best deal. The only caveat to buying something from the business section is you will need to add a business name to the order and just like a business credit card, this can be anything, ie: Joe's Deli.
There are
always coupons out there, some are posted straight on dell directly at certain items:
Others have to be found (GYIF) and even if it doesn't list a code on the item per se, it can't hurt to try it anyway.
Fun fact, the code 50OFF699 applied to my order even though it wasn't listed but remember to enter codes in order. First, I entered 50OFF699 and then STAND4SMALL (thanks
@Dan !) if I would've entered those in reverse then the total would've been less then $699 and the 50OFF699 wouldn't have worked.
Also, if you have not already, join the
rewards program it's free money like any other rewards program albeit they expire.
Maybe this should be wiki'd especially the current promotions like this incredible
amex offer and this
awesome 10% off code
