How the substitution price promise works

Our Sainsbury's (Substitutes Price Promise) applies to substitutes you decide to keep and works like this:

If we offer a substitute costing more than the grocery item you ordered and you keep it then we'll give you a voucher (up to a maximum voucher value of £99.99 per order) for the difference to be used against a future Sainsbury's online grocery order.

We'll email you an evoucher code and will pop a copy in your online voucher wallet. You can find your voucher wallet at online checkout.

The voucher can be used for online groceries only and won't expire for 2 months.

If we offer a substitute costing the same as or less than the item you've ordered and you keep it then we'll charge you for the item we deliver. We won't consider this item or make any deduction when calculating the value of your voucher for any other substitutes;

We'll calculate the value of the voucher by comparing the price of the item you ordered with the price of the item we delivered.

We'll tot up the total for the substitutes you keep and send you a voucher for this amount.

We'll include any multi-buy promotions and offers in the comparison so if you order two items on multibuy and we only have one item in stock and we offer a substitute for one or both items, we'll offer you a voucher for the difference between the multibuy price and the price of the items you keep.

Comparisons based on our in-store price on your delivery day.
