The 'buy it nice or buy it twice' is an old adage that simply means, if you buy something 'cheap', there's a chance that it won't last you as long or won't be fit for purpose, so you'll end up buying it again. If you 'buy it nice' you'll save yourself hassle, time and money in the long run.
It's about intentionally shopping, aiming to make sure you don't make a mistake buying products that might not be of a great quality. But, they also don't have to be the best. While it's still relevant today, there's some flexibility given the modern day landscape of fast trends, online shopping, and the increase in cost of living.
