The category you don't carry is the customer you don't keep
Customers leave when you fall short
When shoppers can't find what they came for, they go to a competitor who has it, and acquiring them back costs far more than the sale you just lost.
Competitors are expanding faster than you
Digital-first players add categories in weeks. Every quarter you spend sourcing and stocking is market share handed to someone more agile.
Expansion risks your margins and your reputation
Betting on the wrong category ties up capital and clutters your brand. Get it wrong, and you've damaged both your balance sheet and customer trust.
