You've got to try them! I've been a fan for years... I think it depends on the season (or how deep into winter we are) what you can get but I particularly love the Peach Ginger, Strawberry Lime Rickey and Black & Blue, although my last jar of B&B was a bit seedy for the first time ever. Maybe it has something to do with the growing season.
Bonnie is from Cambridge and she does a lot of tastings and classes in the area. I've talked to her before and she is really obsessed with good fruit. She says she picks the best fruit and she doesn't use any pectin in her jams and you can really taste the difference. The fruit flavor is surprisingly intense.
The red pepper jelly is great too but it's not as widely available. You can probably get it online at her website though, I think it's just www.bonniesjams.com
Bottom line... give it a try!
