Yeah, I've got Prime. However, when I've been looking the last couple of days, they've been $11.62 a plug.
Then, I got all excited about the B2C vendor link there, where the plugs were ~$8.50. However, the general consensus was that they were scamming and sending people the wrong plugs. So, I passed on them.
Ultimately, I saved about $15 going the route I did. We'll see whether it pays off
I'm not too concerned about the vendor--just thought I'd let people know I didn't have any prior experience with 'em. I did do a quick search and found a very positive BBB entry. Worst case, I paid with the AmEx. They're good about backing the cardholder
