Asda online grocery shop, need a question answered please.

[npg1]

Can you log into your account and keep adding to your shopping several days before its due to come like you can on tesco?

I normally use Tesco but want to try asda but what I tend to do is book a slot and keep adding to it over several days and not sure asda allows this? Also how much is delivery please?

Yes you can but you need to go throiugh checkout each time I think. You need £25 minimum before you checkout though
