I responded, "It's not that Friday, Saturday and Sunday are almost double the price of Monday through Thursday, it's that week day weddings are almost half the price of weekend weddings."
Although my comments were tongue-in-cheek (and I did follow up with additional information waving off the literalism of "half"), there is some truth to the way I phrased it. Most wedding professionals consider their weekend rates to be their standard prices simply because that is when they do the bulk of their work. They honestly do not see it as inflating their fees for peak weekend times, but rather may be willing to discount a fair wage for off-peak weekday events. Notice I used the word "may." Keep in mind that a company's cost of doing business doesn't decline simply because it's Wednesday rather than Saturday. Their supplies, employees, transportation costs, etc. are not day of the week dependent. The amount of work they do for a Tuesday wedding is no different from a Sunday wedding either.
While some may gladly discount during the week, wedding professionals do not reduce their rates by half and should not be asked to do so. Remember your vendors are typically small businesses or sole proprietors who strive to strike a balance between providing a good value to their customers while making a fair profit that translates into a living wage. When is the last time you saw a wedding photographer, DJ, caterer, or officiant listed in Forbes top 500 wealthiest people?
A week day wedding is a great way to optimize a wedding budget, though there are pros and cons you should consider to decide if it will work well for your needs and expectations.
* Some wedding professionals and venues do offer discounted prices for their services, though not all.
* Guests may be unable to take off work or travel during the week, so a cherished friend or family member may not be able to attend.
