Most electronics follow a predictable cycle. Prices are highest right after a launch and drop in the months that follow, especially when the next model is announced.
The biggest sale events are Prime Day (usually July), back-to-school (July–August, great for laptops) and Black Friday through Cyber Monday (late November). Boxing Day and end-of-financial-year sales (June in Australia) are also strong.
Rule of thumb: if a new model is due in the next two months, wait. Either the new one is worth it, or the old one gets cheaper.
Black Friday vs Cyber Monday: which has better deals?
These days they're mostly one long sale. Many deals start a week early and run through Cyber Monday at the same price.
Big-ticket items like TVs, consoles and appliances tend to be strongest on Black Friday itself. Cyber Monday leans toward smaller tech, accessories and online-only deals.
Don't trust the 'was' price. Check the price history before you buy — some 'deals' are back to a normal price after a quiet price rise in October.
