I got vanity plates about 5 years ago and they definitely had Bills plates with a helmet on the left of the plate.
I couldn’t think of anything personalized that I wanted to do that wasn’t already taken, so I scrapped the idea.
To get a Bills plate with a personalized number is a double hit to the wallet, too.
I opted to just do a personalized letter/number combo (Mets related) on one of the blue/gold plates.
I think it’s an additional $60 every two years, but I could be mistaken.
If I’d have gone with a Mets plate AND the personalization, it would have been at least double that amount.
