I came here because I thought Galleria may have two certain products P.A.T. may not carry. I found one of the two products, but they refused to sell it to me because it wouldn't scan properly. I offered to go and take a photo of the price tag, but they just repeated "we can't sell this to you". Also super cramped spacing.
I ended up going to P.A.T. after, they had both things I wanted and the staff are super friendly as always. I definitely prefer P.A.T., especially now that they are renovating their Mississauga location.
