I have an Asda annual pass (won't be renewing, they're a bit rubbish locally). I've never been subbed up, e.g order a small pack of own brand nappies, if they are unavailable they'll never send a big pack, or Pampers or whatever....I struggle to believe there are no size 5 nappies in the store, just that they have a policy of not subbing for something more expensive than you ordered.
I'm really not a cf after a freebie, but it's frustrating not getting a key item when I'm trying to stop the deadly top up shops.
Are any supermarkets particularly good / bad for subs, or does it vary store by store?
