I know mumsnet are partnered with Babyetc and offer a 10% discount but I honestly wouldn't bother using the company. I ordered a cotbed mattress, they promised 48hour delivery, took payment (not cheap even with discount) then proceeded to keep promising delivery and nothing happens. I spent 4 days waiting in for promised deliveries, made 8 phone calls chasing them eventually to be told "sorry, don't have stock and not getting any more in, have a refund", this was 2 weeks AFTER they had taken my money! Had to then make ANOTHER call to chase up the refund. Useless communication, useless customer service and I doubt any of them actually know how to pick up a phone and ring the customer.
My advice - shop elsewhere if you actually want to receive your order
