Haven't gone through the 37 pages but here's mine for Disposable Heroes Comics (based in Belfast, Northern Ireland, sure to be sure
)
Packaging - for 1-4 (or5?) they use the A194 Cardboard envelope, which is about 1cm bigger all the way around than a comic (which are always sent bagged and boarded). Envelope is sturdy and gets here in perfect condition about 99% of the time. The odd occasion it arrives with a big fold through it, that creases the inside comics too, well I put that down to postman being a dick
rather than inferior material. I've got a pillow under my letterbox as I'm sure the odd envelope travelled thru the postal system un-scathed, only to land on my floor on its corner, denting said corner and giving the inside comic a slight dent that is most frustrating.
For more than 4 they use one of those cardboard folding type things I sure all comic buyers are familiar with, sturdy as heck, haven't failed me yet.
Refunds - on the SINGLE occasion nothing turned up (been buying from them for maybe 5 years) was the time I said "Hey, don't send them weekly, save yourself a bit of money and send them all in one huge monthly parcel". Nothing arrived, so I rang up and a replacement swiftly followed. - went back to weekly deliveries after that debarcle.
Oh yes, and one time I bought a Judge Dredd Blank Cover Issue, without understanding that a Blank Cover Issue was exactly that, no picture, just a blank space. They offered to replace it (nice chaps) but the cost & hassle of returning it was, well I couldn't be assed so sucked it up. It was nice of them to offer.
Any email queries usually get a reply within a day or so, and their site lets you pre-order a couple of months in advance. Will soon be doing that for those Convergence #2 tie-in issues.
Oh yes and they offer free post and packaging too, which can't be nice for them when someone only buys a single issue, but I ain't complaining.
[edit] one time I eBayed a NM issue to fill a long-time hole in my collection, only to have the seller send it unbagged and unboarded, with a cardboard insert SMALLER than the comic and containing a pre-existing fold the length of it - giving NO protection whatsoever and almost DEMANDING the postman folds the darn thing. Seller deserved a slapping.
