Walmart to Offer New iPad Beginning at 12:01 AM Local Time
If you want to be the first person amongst your friends and colleagues to have the new iPad, you will need to head to your local Walmart. Starting at 12:01 a.m. local time on March 16, a limited supply of the new iPad will be available at your local 24-hour Walmart. Other retailers’ doors don’t open until 8 a.m. local time, so you can get to work on time and beat the rush by coming to Walmart.
Several retailers in Australia also offered midnight sales of the new iPad, meaning that some customers have already been able to purchase the device. The teardown experts at iFixit were first in line at a Telstra store in Melbourne and have been dissected an LTE iPad over the past several hours.
