Money is not exactly flowing, but DD needs new ski suit and DH has a 20% discount for the sports shop near his work. The idea is I'll take the DC there after school, he'll meet us put it on his credit card and drive home together. If we buy only the ski suit, probably our train fare will cancel out the discount.
DS is 142 cm tall. His rain coat is size 140, it's still wearable but is getting on the small side. I thought maybe we should look for one now, but he doesn't actually need it yet. He already has a proper winter coat but it's only showerproof. It would put a strain on the month. But the discount voucher is only valid until the weekend.
Or, I take the DC to the same shop near us (bus fare), but where the offer isn't valid, make them try on everything and tell DH what to buy. then it definitely goes on his card!
