Common promotion errors

With all the different ways you can offer discounts, ensure that every promotion and sale makes sense. Here are some common mistakes to avoid.

Promotion Type	Reason this is wrong	Solution
Buy 1 for $4	This isn’t a promotion because it only applies to one item.	Remove the promotion fields and adjust the cost_price_per_unit or sale_price column.
Buy 2 for $3 where cost_price_per_unit = $1.50	The customer doesn’t get the deal because two times the regular price is the same as the promotion.	Remove the promotion.
Buy 2 for $5 where sale_price = $1.50	A promotion and a sale are running simultaneously. The customer pays the lowest price, or 2 x $1.50 = $3. The promotion displays on your storefront, but it’s a poor customer experience because the promotional price is greater than the sale price.	Remove either the promotion or the sale.
Buy 2, Get $5 Off where sale_price = $2.00	A promotion and a sale are running simultaneously. The deals stack, which entitles customers to both discounts. The resulting price is negative. 2 items x $2 = $4 $4 - $5 = - $1.00	Remove either the promotion or the sale.
