They don't get any from other people, and it wouldn't occur to me to buy Easter Eggs for anyone else.
This, yes. I think it's possibly regional as DH remembers getting chocolate from everybody as a child.
I got my arse handed to me on AIBU a few years ago for asking if I had committed a massive faux pas by politely declining a neighbour's offer to buy each of my DC a full-sized egg. I was solely responsible for the death of community 
Warning: spoilt FWP starts here.
glueandstick - yesterday evening DH casually said "I haven't got you an Easter egg". My eyes widened in horror and my lip wobbled.
"But ... but ... We talked about this! If you don't get me one, I won't have one. And I'll have done and I'll get nothing."
He went to the supermarket. Then a second supermarket in another town. Then a third supermarket in the village near us.
"The first one didn't have anything suitable, then the second one had nothing at all. I got you the right kind of thing in the third shop. It is the right thing, isn't it?"
Alas no because he rejected all the completely perfect 99p Smarties ones in the first shop, and got me a posh one in dark chocolate. Fortunately I saw it when I was alone, otherwise he would have seen my disappointment. And even more fortunately he also bought a big box of Maltesers.
But I'm gutted that he wasted so much time rejecting the right thing (thin curved everyday chocolate) in favour of the wrong thing (nice chocolate artificially adulterated and glazed so as to be inedible). When he could have BLOODY LISTENED to my long explanation of my need for the former AS HE WAS LEAVING TO GO TO THE SUPERMARKET EARLIER THIS WEEK.
There is other stuff going on that means minor disappointments are hard to tolerate at the moment.
Anyway, combine "far far too much chocolate I do like belonging to the DC" on the one hand and "chocolate I don't like belonging to me" on the other and you'll have a glimpse of my agony.
For reference: I hand made his Easter egg.
