A big thank you to all our amazing customers for supporting small, local Aussie businesses during this year's Black Friday and Pre-Christmas Sale season!
We know it can be tricky to compete with those big, multi-national companies.
Remember, small businesses like ours are the heart and soul of Australia! So when you get the chance to choose between supporting local folks or international billionaires, think about the lasting difference you can make.
Keeping profits in your community means more jobs, support for hard-working families, and it helps other local businesses, plus sponsoring sports teams and charities we all care about!
So, if you've loved any of our products, could you simply tell a friend or family member? Sharing a kind comment or showing off your new Thermal Theory trackies, leggings or jumper that you're wearing, doesn't cost anything and we would appreciate the support.🩵
Regards,
Eulia (Founder - Thermal Theory - Kangaroo Island, South Australia)
