App ordering X:LTE or WiFi?

Ordering with Apple Store app, better to use LTE or WiFi?

Thinking of using LTE on my phone and using Apple website with laptop wifi as a backup, but not sure if LTE will be saturated with everyone ordering.

Use the app on Wi-Fi and, earlier in the day, save as a favorite the item you plan to order.
