💡 Shopping Tips- Bundle multiple projects or supplies in one order to make the most of any free-shipping threshold.
- Compare active promotions against seasonal sale events before buying, since stacking multiple codes isn't always allowed.
- Read the return and shipping policy first, especially on discounted items, since sale orders sometimes carry different return windows.
- Add items to your cart and check back the next day; abandoned-cart follow-ups sometimes include a surprise discount.
