Berkley gulp rebate. Am I reading this right?

So for the next few weeks Berkley is giving a $10 mail in rebate for purchasing a Berkley gulp alive pint. Most pints are $20 so it's essentially half off, but a couple of the pints are $10.49 (see link), so if I'm reading this right, you are getting the pint of shrimp for $.49 (I think it also had free shipping). Am I missing something or is this a reeeeeally good deal?

It would appear that the $10.49 is the discount price, and a very good buy.

I decided to take the chance and get two half pints at $5.23 each.

I tried to place an order today for 5 jars and their online system would not process the order and I was instructed to call their 800 number but they are not open on Sundays.

Mine went through okay. Maybe just an issue with the website.
