Had an email this morning saying : Action Needed: Update your shipping prices. We removed the ship options for your seller-fulfilled products with excessive shipping prices. Affected ship options are reflected in the following table:

Has anyone else recently received this email because I can't find any items where my shipping costs are excessive? My items are a combination of either Free delivery, or £2.80. Two-Day Premium Shipping we charge £4.99.

I've been through my shipping settings etc but am totally confused..
