The wording of Precision Delta's shipping and minimums policy is a little vague.
Bullets must be ordered in multiples of 2,000 (calibers and bullet types can be mixed and matched by the 1,000). If your bullet order totals an odd quantity, we do charge $5 (this charge will not be reflected in your shopping cart but will be charged when we process your order.)
Quantities of a thousand automatically get free shipping. I would have expected them to charge you the $5 on that order though.
BTW, my last order from them was for 2000 bullets. It came in a USPS flat rate box. My route deliverer usually brings packages to the back door. She had a heck of a time with that box. My wife didn't even try to pick it up. They get their money's worth out of those flat rates.
