Forget the official stuff. If you really want to remember the big day, why not splash out on souvenir loo seats, condoms or sick bags.
Kate and William have approved a number of items as official souvenirs - including china plates and monogrammed tankards - but it seems some retailers are willing to slap the couple's names on just about anything in the hope of making a quick buck.
Some are kitsch, others are verging on the plain insulting. Amazon and other web shops have a white loo seat featuring the grinning couple for those wanting to give their own porcelain "throne" a royal makeover.
If you prefer to lie back and think of England as Wills and Kate tie the knot, some Crown Jewels condoms might come in handy.
Available in boxes of three or nine, each condom is decorated with a portrait of the royal couple.
