Who buys hath need of a hundred eyes. Who sells hath need of one.

A purchase demands careful attention because the buyer must judge what is being offered before committing. The hundred eyes exaggerate the degree of scrutiny advised.

The contrast with the seller’s single eye suggests that the two parties do not face the same burden of inspection. It urges buyers to look closely without necessarily accusing sellers of dishonesty.

Use it to caution someone considering a purchase, especially when the condition, quality, or terms deserve a closer look. Its pointed contrast suits advice about checking before agreeing to a deal.
