Clarification of Material Status for WSF

Is WSF 10 working days like the materials status page says or 8 working days like my cart says?

It's a minor discrepancy but it's kind of bugging me. I feel like it should be one or the other but not both! Any possibility of clarifying this?

It should be 8 working days at them moment

UPDATE: Sorry coolbutpointless it is a little confusing but, in the shopping cart it states 'ready for shipment in 8 working days' but delivery time on the materials page is 10 days.

You will also note that in the shopping cart you will have a notice like "Your order will be delivered on or before October, 27th" directly beneath all of your items ordered, which will default to the material with the longest lead time as we ship all items together.

This is a little confusing, we will clear this up.

Thanks for pointing out.
