When you purchase a discovery set of 2 mL spray samples of the entire Maher Olfactive line (permanent editions) in a hinged metal tin, you will receive a $35 credit to go towards the purchase of a full bottle.
However, you must opt-in to receive marketing emails at checkout to receive your discount code via email. Simply check the box and it'll send an email. However, there has been a bit of a technical glitch with Shopify's new Shop Pay checkout option. If you do not get an option to opt in, please email me at email@example.com to get a discount code. Sorry for the hassle. I am currently trying to get an answer or solution on this.
The Discovery Set contains everything in the regular lineup but does not include special limited editions.
