When planning your wedding budget don't forget to factor in the cost of posting your save the dates, wedding invitations and thank you cards, and if you're feeling generous then a pre-stamped RSVP. 

I got caught out by this when planning my own wedding, as I didn't factor in that the personalised magnet I included would take me over the maximum 0.5cm thickness for standard letters. So make sure you think about the weight and dimensions of your stationery so you don't get a shock at the post office.

My A6 and A5 wedding stationery options both fit within the standard letter size predefined by Royal Mail (see below) but if you're planning to add any embellishments like a bow you may have to pay out more for postage because of the depth.
