Same Beer Different Stores Different Taste?

My favorite craft beer store is 20 minutes from where I work. I work 5 minutes from home and would like to grab a beer without going out of my ways sometimes so I go to the liquor store across the street that has decent selection of craft beer but i have no idea what the turnover is. Let's just say craft beer isn't the main market for this place. Anyway I picked up some zwiec porter which i've had today and I swear it tasted different somehow and I threw out half the bottle. I'm drinking a two hearted right now that was bottled 2 months ago and it doesn't taste anywhere near as good as I remembered it. Am i imagining things or is it possible that the same exact beer can taste so much better if i buy it from a liquor store 20 minutes further away?

 

Probably the bad one mostly caters mostly to bmc while the good one has an entire wall dedicated to craft
