Out of five recent expedited BDs from Amazon, two have arrived on time (both Mrs Q's rom/coms ), the other three about a week late (two DHL and one with i-parcel).
Another "expedited" BD due in May turned up after 14 weeks - its replacement arrived a month earlier. DHL underperforms yet again - I groan every time I see those crooks named in a shipping notification.
I always chase a shipping refund so Amazon keep pressure on their unreliable shippers i.e. those ****s at DHL who are the very regular offenders.
I generally fork out for expedited, but lately, the shipping times have been woeful and the tracking is no help at all.
I've had 4 shipping refunds out of 10 discs in the last 2 months. Hopefully, this won't continue, especially now that so many blockbuster films are being released in Australia almost simultaneously with the States (though I still am an advocate for US releases - almost always better).
