Amazon.com is refunding shipping charges and giving shoppers $20 gift cards if their holiday packages didn’t arrive by Christmas as promised.
An Amazon spokeswoman declined to say how many customers had been impacted or offered such a rebate.
The rebate news comes as United Parcel Service determined late Tuesday that it wouldn’t deliver some goods in time for Christmas, as a spike in last-minute shopping overwhelmed its system.
“The volume of air packages in the UPS system did exceed capacity as demand was much greater than our forecast,” a UPS spokeswoman said.
Consumers were reporting missing deliveries from FedEx as well, although a FedEx spokesman said the company wasn’t experiencing significant delays.
