Wedding poem and how much to give

[WeddingGift]

So I've received a wedding invitation with this poem;
We've lived together quite a while
With all our pots and pans
And as we don't need homely gifts
We've got another plan.
We know its not traditional
And not the way it's done
But rather than a wedding list
We'd love a bit of sun.
So if you'd like to give a gift
And send us on our way
A Thomas Cook Voucher
Would really make our day!
But the choice is really up to you and we would like to say
That the best gift we could receive is you here on our special day!

I don't know how much to give! I also hate being asked for money as I feel it's like putting a value on the friendship to some people. I would describe the friend as a good friend and we've known each other a year. I would much prefer to give a gift but feel this may be bad etiquette? I've only been to one wedding and they had a gift list.
For context my dp earns around 25k and I earn minimum wage whilst looking after our 1yo. We are in the process of buying our own home so not loads of spare cash.
Thanks!

I'd give them a card with a poem inside, telling them the cheeky feckers you've taken their advice and booked a sun holiday with Thomas Cook. ...for yourself and your family.

£20 is a lot of money! Im getting married and have asked for money instead of gifts as we already live together and have all household things we could need. Id be more than happy if my guests all gave £20! x

Bamba YABVU. We all love a good grabby entitled wedding poem. Op's friends are rude beyond comprehension. They should be embarrassed.

I'm not a fan of various family members being Mormon (cult!) members, but I do so appreciate their very family and community oriented weddings, few gifts and non expected, community made buffet meal and your being there truly is all that's wished for; no way I could've gone to any of my cousins weddings had their been some huge expectation of large cash gifts as we don't live all that close so travel and overnight stay was needed, and being disabled and unwaged, would've had to say sorry can't go if needed to find lots of cash for gift as well.
£20 is fab if that's what you can afford op, Id love personalised vouchers like a number of times babysitting / help in my garden / a massage etc (depending on your skills obviously) even more from friends / family I knew weren't well off

Most friends at our wedding gave £20-£30 so yours seems perfectly reasonable to me. One of the best was 2 couples who clubbed together and gave us £60 between them. Weirdly felt more than if they had done it separately. Do you have anyone you could do this with?

OP I do think that most people genuinely mean it when they say that they don't expect anything and would just be happy with your company.

I certainly am more grateful for the people who were still dancing and having a great time at 1am, helping us make great memories, than those who gave the largest gifts.

We also directed people towards a monetary gift when we sent invites. Personally I don't like the poems but I know that some people just think they sound more polite than 'if you want to give us a gift, we would prefer cash'.

If I really had to go I'd take a nice bottle of wine but that's it. Hate cash requets, vulgar and grabby. If you don't need anything then you don't need money either.

If a couple can't afford to feed you then they need to scale back or save longer.
