I've never had a significant problem with Currys, either.
Last year, our freezer, fridge and diswasher all gave up the ghost, a few weeks apart. We're planning on reconfiguring the kitchen in a couple of years, so wanted the cheapest, basics for replacements.
All 3 are Currys Essentials, cheap as chips and perfectly functional . I stock checked online, picked them up myself (in each case, helped by nice, polite young men!) brought them home, unpacked them and DP and I removed the old ones and put them in their spaces.
The only problem I had was when I paid for and reserved a new tv online, drove 20 miles to the nearest branch to collect it and found it was out of stock (this has also happened to me at Homebase, B&Q and Argos).
They found the same model at another branch and arranged for it to be delivered the next day, free of charge, and they arrived on the dot of 9.00 with it, as requested.
I had no idea they had such a bad reputation.
