J & L Industrial is having their "25% off five items or more" sale starting today through Wednesday. You can pick up the Starrett straightedge and four other tiny items and get a pretty good deal. And hell, they've got ton of stuff I always seem to need anyway, so now may be the time to cleanup.
Enter 25WSPE in the Promotional Code box on the shopping cart to get the discount.
They also offer free upgrade to overnight shipping (from regular ground rates) if you request it.
Let me know how you like it.
