When you buy a card, you select an amount to load. That value is stored electronically with the retailer. Each time the card is used, the purchase amount is deducted until the balance reaches zero [7].

: Always save your purchase receipt as proof of ownership in case the card has technical issues [3].

: You can buy cards in-person at physical stores or through their official websites. For example, Lululemon offers both physical cards in-store and eGift cards online via their partner, CashStar [13].
