The way I see it is it's like going out for dinner
If you go to Trader Vics at the Bayshore-your gonna get excellent food and great service
If you go to Mcdonalds your gonna get crappy food with usually crappy service
If you go to say White Spot your gonna get half decent food at a half decent price
So purchasing demands are going to depend good quality, service, budget, and and time factors
If I'm in a rush and need a half dozen hermits, then I don't care if I have to stop at the "drive through" LFS
If I have a whole wack of time and I'm looking for something rare then I will shop at the "fine dinning" LFS
And finally I will most often settle with the "famliy style resturant" LFS for most of my day to day purchases
