A few options on SALE at Platypus.
I purchased a PUMA Roma days ago ($69.99) as I wanted new sneakers. Very happy with that.
Multiple options and sizes, some up to 86% OFF. Superga, PUMA, Reebok, Timberland, CROCS, Converse, etc.
Full-priced Reebok have 20% OFF with code REEBOK20
I believe that's SALE but not related to Boxing Day as there is nothing suggesting otherwise, and I purchased the Roma for this price on Sunday (delivered on Tuesday).
Free delivery above $150, otherwise probably $10 (based on my location, not sure if standard fee).
