In addition to what others have mentioned, there’s also the 134 bus that (sometimes) serves north Woburn out of Wellington, though it doesn’t connect to Anderson but rather Winchester Center, which is out of commission until further notice. There’s an express bus out of Anderson that goes to Logan airport, as well as Flight Line service to Manchester airport.

 

Burlington has some limited LRTA bus service that goes from the mall/Lahey area to the commuter rail station/LRTA hub in Lowell, in addition to another line that goes to the 3A/62 intersection/concurrence. Both routes go through Billerica, so you could consider living there as well (or even Lowell proper). The Lexington Lexpress has a route that connects to the mall area as well. Burlington used to have its own little bus system called the B-Line but I’m not sure if it’s defunct by this point.

 

To put things in to perspective, getting from Wilmington center to Burlington Mall takes approximately 7-10 minutes by car, while the LRTA trip takes 2 hours and 45 minutes from the moment you get on the first bus. Good luck!
