Contract Law

Pharmaceutical Society of Great Britain v. Boots Cash Chemists (Southern) Ltd.

[1952] 2 QB 795

Citation: [1952] 2 QB 795
Court: Court of Appeal of England and Wales
Date: 1952
Bench: Somervell, Birkett and Romer LJJ

Facts

Boots operated a self-service pharmacy where customers could pick medicines from shelves and take them to the cashier.
Some medicines displayed on the shelves were classified as “poisons” under the Pharmacy and Poisons Act.
The law required the sale of such medicines to take place under the supervision of a registered pharmacist.
A registered pharmacist was present near the cashier and supervised purchases before payment was accepted.
The Pharmaceutical Society argued that the contract of sale was formed when the customer took the medicine from the shelf.
On that view, the sale would occur before the pharmacist had an opportunity to supervise it.
Boots argued that the display of medicines on shelves was not an offer.
According to Boots, the customer made the offer to purchase at the cashier, and the shop accepted or rejected that offer under the pharmacist’s supervision.

Issue

Whether the display of goods on self-service shelves amounted to a legal offer, so that the contract was formed when the customer selected the goods.
Alternatively, whether the shelf display was only an invitation to treat, with the customer making the offer at the cashier.

Rule

A display of goods in a shop is generally an invitation to treat, not an offer.
An invitation to treat invites customers to make offers but does not itself show a final intention to be legally bound.
The customer makes the offer to buy when presenting the goods for payment.
The shopkeeper may then accept or reject that offer.
A contract is formed only when the shop accepts the customer’s offer, usually at the checkout or cashier.

Application

The Court examined the practical operation of the self-service system.
Merely taking an item from a shelf could not amount to acceptance of an offer because the customer had not yet finally committed to buying it.
A customer might:
change their mind;
return the product to the shelf;
replace it with another product; or
discover at the cashier that the item could not legally be sold to them.
If the shelf display were treated as an offer, the contract would be formed immediately upon the customer picking up the item.
That would produce unreasonable consequences because:
the customer could technically become bound before reaching the cashier;
the shopkeeper would lose the right to refuse the sale;
the customer might be accused of breach merely for putting the item back; and
regulated goods could be sold before the pharmacist supervised the transaction.
The Court therefore treated the shelf display as only an invitation to customers to make offers.
The customer’s act of taking the goods to the cashier was the actual offer to buy.
Boots accepted the offer only when the cashier processed the purchase.
Since the pharmacist was present at that stage and could intervene before the sale was completed, the statutory requirement of supervision was satisfied.
The Court also recognised that self-service shopping did not change the traditional legal rule governing shop displays.
The physical arrangement of the store was commercially different from an old-fashioned counter shop, but the legal structure remained the same.
The shop was not bound to sell every item to every customer merely because it had displayed the item.

Conclusion

The Court held that the display of goods on the shelves was an invitation to treat, not an offer.
The customer made the offer by presenting the goods at the cashier.
The contract was formed only when Boots accepted that offer at the checkout.
Because the pharmacist supervised the transaction before acceptance, Boots did not violate the statutory requirement.
The case established the leading rule that goods displayed in shops are ordinarily invitations to treat.
Use this case for: a shop display invites offers; it does not itself create a binding offer.
