Prices are what each store's own site showed at our last daily check (6 November 2026), before delivery, and they can change at any time: the store's checkout is always the final price. Delivery costs are each store's own quote for a small order to one city in your region, checked weekly; they can differ for your address. Every store listing here carries this product's barcode (3701415902596), so it is the same product and size, not a look-alike. Multi-buys and free gifts are what the store's own cart charged for 1, 2 and 3 of this product in the last two days; stores stay in single-item price order. Buying several products?

How do you know every store sells the same Initio Side Effect (50ml)?
We match listings only by the barcode printed on the box (3701415902596). A listing without that barcode is left out rather than guessed, so other sizes, refills, old packaging and look-alikes never get mixed up.
Are these prices with shipping?
The prices are each store's own listed price, before delivery, and they are sorted by that price. Under each store we show what delivery cost in that store's own quote for a small order to a city in your region (checked weekly), and from what order total it becomes free, when we know it. Your address can change the cost, so check the store's checkout before you buy. Buying several products? The basket compares whole orders with delivery.
