What should I do regarding me buying an Apple gift card and to only find out the card wasn’t inside the packaging? I have looked on my receipt and high and low for the card in the package, receipt and everywhere else but there was no card to be found

You will have to deal with Dollerama's management in order for them to refund or replace the missing Apple Gift Card. No one here, not Apple can replace this card. However, you can still try contacting Apple Support to see if they can offer any assistance with this matter. To do so, simply select the "Support" link on the lower left-hand side of this forum's web page.

One other thing. As it's been awhile since I have purchased a physical Apple Gift Card, to the best of my knowledge, they came in a wrapped package that clearly shows the card. Was this not the case?
