I'll let you into a little secret. When certain items are put on special offer, they bump up the prices so it seems you are getting a lot free, when in actual fact, you are actually paying full price for both. All those bottles of wine at half price, £5 a bottle, they were never on sale at £10, they are specials that you won't find on the shelf otherwise. Meal deals where the bottle is £8, it's never that price, but it looks like you are getting a great deal, so it sales.
Suncream is an easy target, it's seasonal, so the special offers are brought in straight away, so no seeing the proper price beforehand. Anyway, ownbrand stuff is just as good in my mind, except always get a waterproof one for your face or you'll end up with stinging, watering eyes just as you reach the crux!!!
