My wife and I always go shopping together but when we arrive at the Mall we part for she loves clothes shopping while I hate it.
I always head for the large electrical stores with the huge Currys store at Cribbs Causeway, Bristol being a joy to my eyes, and I can well spend hours in there losing all concept of time.
My wife usually has to fish me out of there when she has completed her "rig out shop" or rings me to say she will meet me in some restaurant or pub etc.
So that is how we maintain "married bliss" on our shopping trips. ?
Oh forgot, for Christmas shopping, we always make it a weekend away. Last year we went to St Ives Cornwall. There are some wonderfull little gift shops in that town and the other small resort towns of cornwall where you really can get something different to the same run of the mill stuff you find in the big chain outlets.
The above makes for a lovely trip and hotel weekend and shopping together a pleasure.
Shopping together, key is, think outside the box. ??
