Weddings are expensive, and some people are trying to cut corners every way they can. If you are trying to save some money, it’s better to do it on some things that are not so obvious and in plain sight. Decorations in dollar stores look cheap.
It’s like they want to look expensive and flamboyant but in a really clumsy way. That makes them look even cheaper. Also, there’s the quality issue. Most of them are made with inferior materials and procedures and might not even last until your wedding day.
