I personally wouldn't touch Landywoods with a barge pole! They're stuff has been off when it's come here, so I use TPMS.
I usually collect is as there is a gorgeous park opposite which the dogs love, but their deliveries are good (got it delivered when I was up the duff as easier). I don't think there is much flexibility on days to be delivered, I think that depends on your area, but you can ring up on the morning to find out what time(ish) they are due, and they are usually pretty good with keeping time.
I couldn't recommend TPMS enough! They are brill, and have been using them for over 2 years now
