There are a lot of different things here. I got a good deal on my LED Christmas lights. They handled my return of dead lights relatively quickly. The cashiers have always been friendly.
Later in the year, when I was shopping for grass seed, they did help me find a type that works well for allergy sufferers and steered me in the right direction for soil and a seeder.
However, if you have any questions for a staff person, you have to hunt one down. Every single time. Not fun.
Lighting isn't the greatest, but I suppose it's the same in any of these shoebox monster stores.
