thing is - part of the issue is that the op has to travel and stay over. that's as expensive for the evening guests as the day guests, granted - but should they have only invited evening guests who live in essex?
i assume it's being held their because one of them lives / is from there, or because it's cheaper. or both. my sis had her wedding way out in kent because she got to hire a gorgeous 17th century barn conversion for the same price as a pub room in london.
i'd never knock anyone for trying to save money on their wedding. by having it in the styx or having a pay bar or not inviting everyone to the whole day, sit down thing.
i've also been alarmed over the years on urban at the venom and contradictory venom at that, reserved for the subject of wedding lists.
in this case, having more than one store registered seems like trying to make it easier for rellies who don't live near a debenhams or whatever. also - some people prefer buying gifts from practical john lewis rather than poncey habitat etc...
if people ask for vouchers, they're grasping and want to see how much people spend
if they ask for gifts they're grasping because they've lived together years and can't possibly need anything, so why should they get a nicer toaster that we've got... grumble, mutter...
some couples ask for a contribution to the honeymoon, which i've seen decried as horrific greed or lauded as an excellent idea.
i've never objected to buying a wedding gift - but when i haven't afforded it, i haven't done so.
you were invited and a suggestion was made for gifts. it's not a condition any more than you had to accept their kind offer to invite you in the first place.
should i ever get married, i really bloody hope no one comes under sufferance because we haven't made the offer attractive enough, or we asked for the wrong gift.
oh - and the high heels thing? it's advice. so you can have fun. at the ceilidh.
