Yes, the pretzels are dipped in a lye bath before baking as it is customary in Germany.
There is a large selection of German specialties at Annelore's bakery, but if you only want pretzel rolls, it's best to go to Lidl. Lidl has German-style pretzels and rolls. There isn't a large selection, but it tastes very good and it's a lot cheaper than Annelore's.
You have to call the store. The bakers don't read these questions.
