The only real deals are the damaged or slightly damaged appliances.
After comparing flyers and websites, you can get a better price for better quality appliances at other stores when they have sales (also try speaking to the store manager for a better price if you are buying multiple appliances).
Paddy's Market isn't really worth the drive, unless you want slightly damaged appliances for an okay price - for a basement or something.
I also bought items that I had to pick up from their stock building at the back, the stock building staff aren't friendly and are very slow.
In-store customer service is pretty hit or miss.
