if err != nil Developer T-Shirt
if err != nil is how Go handles errors: functions return an error value alongside their result, and you check it, right there, every time. No exceptions, no try/catch — just an explicit branch after each fallible call.
The most-typed three lines in the language, loved and grumbled about in equal measure, and the clearest expression of Go's preference for the obvious over the clever.

Shipping and returns
Shipping costs vary by region, so it's worth giving the delivery total at checkout a quick look before confirming your order. Some variants may show limited availability in certain locations—if fulfilment isn't available in your region, our suppliers will try to ship globally from the nearest facility that can produce that specific item. When this happens, delivery costs may be higher than expected due to the increased distance.
We're constantly reviewing suppliers and expanding fulfilment options, and new routes may open over time.
