What’s Changed with Amazon SFP
Weekend Fulfillment Requirements
Sellers are now required to support weekend fulfillment and order pickup within their SFP network as shipping speeds are now measured by calendar days vs business days.
New 1 and 2-Day
Delivery promises are now measured by time in transit days and compliance is based on the percentage of page views that display a 1 or 2-day delivery promise.
for Oversized Only
Amazon standard items must now support nationwide 1 to 2-day delivery while oversized items (greater than 20 lbs or 18″) can support a regional SFP network
