I sent off one parcel earlier this year and am about to send another.
I didn't include any of my details as I assume they don't want to waste money on acknowledgements.
But I'm just a tad wary of continuing to send stuff when it' s hard to know if it's going to the right people /ending up in the right place.
What I've done is set myself a max target of a tenner ( I buy a few things at Poundland) which includes the £2.95 postage. I know you can order directly from their associated suppliers as well.
