What Longmont shoppers say

My experience here was great. The owner was there alone and still chose to help myself and my fiancé go through my dad’s old chest of comic books (probably around 150 of them). He helped us get them inside and then sorted them out for me based on value. He talked to us about them and explained their worth.

I asked for a game for my five and seven year olds and the recommendation resulted in the nicest time we've ever had trying to play a board game with small children. Wide variety of comics too, so there's some my seven year old wants to practice his reading on. Can recommend.
