GROUP BY Developer T-Shirt
`GROUP BY` collapses rows that share a value into one, so aggregates (`COUNT`, `SUM`, `AVG`) compute per group rather than across the whole table.
It's the operation every analytical query leans on, and the one beginners reach for a beat too late — after the numbers come back wrong.
The fabric is slightly sheer and may appear see-through, particularly in lighter colours or bright lighting.

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.
