Swimsuit help

[MuffinToptheMule]

I want to get this swimsuit
www.johnlewis.com/24477/Product.aspx and as you can see on the John Lewis website, there is 20% off today. They don't have my size left though. .
There is a sale because they are 'responding to a competitor's event'. Does anyone know who this competitor could be? I've done loads of searches but can't find any.
Help please.

Also I need to be able to return it if it doesn't fit properly.

Size needed = 32F

Next sell that swimsuit but it's £48.00. Maybe there's a code for a reduction at Next running today?

I think they are responding to Debenhams sale but I can't find that one online
