As an international customer, the holding service is an absolute blessing. Shipping charges really adds up when you buy multiple items per month but now it's ~$6 instead of close to $20 for every order. It's definitely contributing to me buying more games and being a happier customer too. I don't even mind Jotun, or any game, being released alone anymore, it's just a few bucks.
Sure, I have to wait for my games but I never have issues finding games to play.
I haven't had any orders shipped from hold shipping yet, but so far it's great.
It's been $5.50 to ship the order domestically each time and it'll cost I think ~ $22 to ship the package. So it does take a while to start seeing savings, i.e. if you held two games and then shipped them out you'd end up paying more:
$15 x 2 = $30
$5.50 x 2 = $11 + $22 = $33
But the more games you add, the more you'll save. Three would be
$15 x 3 = $45
$5.50 x 3 = $16.50 + $22 = $38.50
And so on. At least, that's how I ended up working it out.
I might ship my parcel of four games out after I get Oceanhorn on the 28th, depending what else is announced for release soon after.
