Each promo code has a unique period of time where it is live and can be used, due to the ongoing promotions and events that are starting and ending throughout the year. This is why it is really important to check back with Mirror Discounts constantly to see the latest promotions and deals on offer for your favourite brands, just like FlexiSpot. You can take advantage of flash sales during weekend or midweek events, new customer codes or limited time exclusive codes, all of which have varying time limits. You can see the expiration date on the Mirror Discounts FlexiSpot page next to each specific code or sale event, so you are kept up to date! Be sure to double check the FlexiSpot terms and conditions for the exact expiration date of the code or event, when you use it to purchase your items at a lower price.
