I know that some posters here wait for this sale to stock up on supplies. It might save you a few hundred dollars in shipping on a larger order.
The code is SP673CA - This is a generic code that should work with every account. I assume one-time per account.
The only hitch is that it is $500+. If you already shop at Uline, you're almost certainly spending somewhere around that per order since everything is in bulk.
