What stands out most about Probey Services is their discipline-no missed calls, no vague timelines, and no surprises.

Stopped in for some Magic card boosters and was greeted warmly by all staff and the owner, who gave me a rundown of upcoming gaming events at the store. I was blown away by the complex schedule they keep - free play, draft play events, and more. The owner gives freely of his time to provide those events, and it's clear he cares.
Perry Review from Google

Perry's Review Sourced from Google
Extremely judgemental, sad, employees. I recently moved to town and came in after work in my business attire. After getting a confused look from the associate up front, (not even a greeting). I started browsing, but everytime I looked up, I was being stared at which made me slightly uncomfortable. I moved towards the back and an associate there said hello, we had a short chat about comics and trading cards but they were rude to a younger customer that came in, it was unwarranted and I'm assuming either this is the employee's normal behavior or an elitist owner. I also couldn't help but wonder if the associate was under some sort of influence. After noticing the trading card prices are exponentially higher than I'm used to seeing in bigger cities, where that sort of pricing would make more sense; I took my leave not purchasing anything feeling underwhelmed. As I passed the associate up front, they still did nothing but continue to stare. Are they not used to the professional community? The store is tidy and organized but cluttered and the atmosphere/vibe is cold. Also not much of a variety for a hobby store. I would much rather take the trip to Milton Freewater to the hobby store there or even Gamestop would be a better choice. I do not see myself returning in the future.
