How do I stop offering wholesale prices on one product?

1. Go to Products → Wholesale Pricing.
2. In Products with wholesale tiers, click Edit next to the product (or open the product's Wholesale tab).
3. Click Remove on each tier row.
4. Click Save tiers.

Saving replaces all the product's tiers with what is on screen, so saving with no rows removes them all. The product drops off the list and goes back to its normal price for every quantity. Other products keep their tiers.
