You would think they have worked out the bugs by now. In the shopping cart, it collates cards to a single address, regardless of the fact they are for different people and you are trying to set different dates. Also in the shopping cart, it wont save my delivery dates and keeps resetting to posting now. Sort this out Moonpig!!!!

Update [31/07/2021]
Moonpig chat on the website were too slow. They say it is less than 3mins, but it is not, I gave up waiting after 15mins. I moved to Funky Pigeon and ordered my cards there. I have been a Moonpig customer for ages (>10yrs), no longer. My (small amount of business) is gone.
