In that case I have trouble believing you're up to date on these matters. I doubt you've even been into one in a decade. Certainly, your opinion on this appears a decade or so out of date.
It's nothing like that in the Dorking branch. You might just want to move out of your obviously fairly common little village into a more sought after area.
Yes, you should. Aldi and Lidl are both fantastic shops - we often go to the one in Dorking, which is a decent size (but probably not much use to you).
The only thing is that you have to be flexible because they don't necessarily stock the same thing week in week out.
