The company's officials apologized and blamed poor planning higher demand and bad weather for the shipping delays.
"They couldn't keep up with the demand. My concern is what they are going to do next year if the demand grows?" Bill Valenzuela from Fresno said.
Valenzuela says he was not affected by the delay, but felt fortunate, since this was the first time he's done holiday shopping online. Other residents Valley residents said they procrastinated and had no problems.
"I got everything shipped to me at Amazon Prime, two days at my house, that was my plan and it worked," Christie Majors from Clovis said.
While some people opened presents with ease, some are still waiting and are not happy.
"Everybody else promised that the package would be here by the 20th and now my kids had to miss a present from Santa," Jennifer Fleming from Winton said.
Despite shipping delays many Valley residents said they will continue buy online and give themselves plenty of time, and also do it in time next holiday season.
UPS did issue a statement Thursday that said:
UPS apologizes to both shipping and receiving customers who may have delays. We had additional sorting operations at Worldport, the UPS international air hub in Louisville, KY, on Christmas and are making deliveries and pickups today. Customers should continue to access ups.com for the most update information."
