I've had a pretty bad experience with Parcel Motel. It seemed like a great idea in the bargain alerts and I signed up and went onto amazon which they pushed as the ideal partner site to use as their delivery costs can be a bit too much for Ireland. I'm not at home during the day and getting stuff delivered to work isnt' always the easiest.
I followed the website instructions and noted that they had differenct sizes of parcel boxes with the extra large suites able to accomdate games console sized items under 10Kg. I ordered a wireless keyboard which came well within all the size limits and was only 1Kg. This was the actual product box size and weight for the item. Even with added amazon packaging it should have still been well below liimts.
A got a text saying my delivery was delayed due to funds lacking. An 1890 phone call later (no local number so money wasted) and it turns out that my package was oversize and that it woudl cost e10.50 to send to another address. So that is e15 for delivery of a 1KG item from the UK. It would have cost half that if I ordered direct from amazon and I would have had it today and not in 2 days time.
BEWARE: These size limits are very misleading. Unless you are in the packing room of amazon you have no idea what size the package is. The suite size boxes are clearly too small for lots of items and you run the risk of having to delay your package and costing you huge money to deliver. Parcel Motel don't really care as it suits them to charge me 10.50 to send an item accross Dublin.
