Crocs Canada has their Mix & Match sale on right now, where you can choose from 60+ styles and get 2 for $40. This offer is available for a limited time, while quantities last.
For myself, I'd grab the Women's Crocs Kelli Flatswhich are regularly $44.99, but now $20 when you buy a second pair of any Crocs from the link above. These flats are super comfortable for chasing the kids around outside this summer.
For the kiddo, I'd grab these Kids' Crocs Bump It Clogwhich come in quite a variety of colour. They would normally be $39.99, but when you pair them with some Corcs for yourself, you'll pay $20.
Spend $49.99 to get free shipping from Crocs.ca.
