Just pondering really.
I tend to go back to UK a lot (visiting family etc) and also stock up on 'bargains' - e.g. toys in the sale/reduced price, kids' shoes (often bought in sale or at a Clark's outlet), supermarket buys e.g. Cheerios, weetabix etc, or Vanish if it's on offer.
It's the sales at the moment in France so I did use some cheques-cadeaux (thank you DH's work - get them before Christmas and they are valid all year!) to buy some Petit Bateau clothes - would normally never buy at full price.
I used to buy nappies in UK but now I just buy them at Aldi as they are cheap there and good quality.
Am always shocked at how expensive fruit/veg is in the local 'primeur' and meat is pricey too. (Ile-de-France area - imagine it is cheaper out in province).
