Printed on glossy card with a jazz hearts theme, you get eight invitations in a pack, along with envelopes.
There are only 2 customer reviews on the Dotcomgiftshop website but they're both positive. Here's one:
"These are really lovely cards, pretty design, high quality card and print, perfect for my daughter's parties."
I don't know about you, but this deal strikes me as bargain-tastic. I never have time to make party invites by hand despite the best intentions, and printing them out on the computer at home would surely cost more than £1 in ink.
I guess the only issue to factor in is that standard UK delivery costs £2.95, so you'll definitely want to buy more than just one packet of party invites to make it worthwhile, but it's worth browsing the site for other party paraphernalia if you're having a bit of a bash, as they do loads of affordable things, from party bags to balloons.
There are several other designs of party invitations on sale for £1 too - check the range available here.
