THE REFERENCE SHELF
Quantity & price
Begin with the selling unit: pair or single
Two pictured earrings do not always mean two earrings in the order.
A single-earring price is not a pair price
A small selling-unit field can change the complete intended purchase cost.
Three dated US offers, with their selling units
A clear comparison keeps dimensions, material and count beside the amount.
Buying two singles needs two-piece availability
Multiplication supplies an amount, not a live stock check.
Plan the piece count before ordering pairs
A small count tool can expose overbuying without assuming your collection matches.
