The best time to buy allergy medication is typically just before peak seasons like spring and summer when demand is high, as HealthExpress often runs targeted promotions. For asthma relievers, look for sales around awareness days like World Asthma Day in May. Stocking up on over-the-counter pain relief during seasonal sales events like Black Friday or the January sales can also yield significant savings.

Yes, HealthExpress frequently runs discount programmes for key workers like NHS staff and for students. You typically need to verify your status through a dedicated portal on their website or by using a specific discount code at checkout. It's worth checking their 'Special Offers' or 'Discount Programmes' page for the most up-to-date eligibility and codes.

While discount codes generally apply to over-the-counter medicines, sexual wellness products, and other general sale items, they often cannot be used for prescription medication due to regulatory restrictions. However, you can usually use discount codes on the pharmacy's service fee or delivery charge associated with your prescription. Always check the terms and conditions of the specific discount code for details.
