Is military discount a thing for suppliers??

It will just be a case of ‘if you don’t ask you don’t get’!

If you are having a venue that is a chain group like Hilton then you may get one, small independent suppliers probably won't but I am of the opinion don't ask you don't get so is always worth it, I don't think is cheeky, them can always say no but they may just say yes!

If you feel it's a bit cheeky to ask, just bring it into conversation. Most wedding vendors chat a bit about your wedding, what style you're going for etc, so it shouldn't be too hard to mention that your OH will be wearing his MILITARY UNIFORM on the day And if they're the kind of place that offers discounts, that should be enough to get you one.

You could try it, but we mentioned that we were having a military wedding to all of our suppliers and no one gave us a discount, nor did we expect one. On the basis that you are generally talking to small businesses rather than big companies, it's highly unlikely it's a thing - I doubt they really have the resources to cover this!

Always ask if they are able to offer any kind of military discount. If you ask in a polite manner, it never hurts to ask and you could potentially save some money.
Also, don’t forget that not everything you get for the wedding will be through suppliers (stationary, gifts, shoes, accessories, etc). If you need to order anything online, have a look on Defence Discount Service first. The card cost £5 and lasts 5 years, but it pays for itself very quickly.
