Just had a caller at the door from Greyhound (in Raheny are) offering 12 euro monthly service, no weight restrictions....
Thats pretty much what I get from City Bin, infact It's €140 per year ... again, no weight restrictions and thankfully, a far better customer experience than I ever had with Greyhound, so there's no way I'd be even entertaining a discussion to be quite honest.
Even if Greyhound offered me a 12-month rate at half the price, I'd be very slow to consider going back to them after my past experience.
They maybe under new management, but they are still under the same ownership (I think) and the owners didn't seem to care in the slightest, about the way their customers were being treated in times past ... infact, I know from personally triying to contact one of them a few years ago when I was a customer, that they had no interest in even acknowledging my letters or returning my calls.
I would sugest a quick phone call to Citybin, tell them the offer you've got from Greyhound and ask them to match it - odds are, they will as they did not have a problem giving me the price quoted above, infact they offered it in return for me paying annually, which I was more than happy to do.
....What can go wrong...
Eh,
Dare I suggest you:
- read some of the past discussion threads on Greyhound,
- or consider what might happen if the dispute with their staff kicks off again and they go back out on strike perhaps ? (granted, thats a risk with any company, but Greyhound do have form

)
