Pre-Order to Avoid Lines and Stores
Pre-ordering the Apple Watch 5 lets you skip the lines and get what you want without going to a store. It's the hassle-free way to get a new Apple Watch.
While there won't likely be lines around the block, you can count on lines on day one at the Apple Store and at some carrier stores, where the stock will be more limited than online.
Since you won't know what a retailer has in stock until they open, you might wait in line and then find out they don't have the model you want.
Skip this hassle and pre-order if you want to avoid the insanity that is an Apple Store or carrier store. This is also great if you live anywhere with hot, cold or inclement weather since standing in line can quickly turn miserable.
