Steam Summer Sale?

Most likely the 19th.

Im not sure but you can buy games via steam app on your phone.

late June or early July, my uneducated estimate.

last year was the second week of july :D

You're leaving on the 17th? I think Steam sales always hit when you are on vacation, so it probably starts on the 17th.

Use the app?

if you can have someone u trust log into your account to buy ur games than...like trust trust...or just use the app or buy a laptop and use wifi

steam sale was never yours to lose...it has you by the wallet the entire time

Unde anume pleci in Grecia? :)

I wouldn't expect summer sale this soon... didn't the last one start like July 11th? Two years ago it could be first week of July, if I recall correctly or 28th June at best.

Probably July as usual

Get the Steam App for ur cell n prepare it for roaming, surfin etc....^^ Everything is possible :P

Do you have any trusted internet buddies? Pay one of them $20-50 and tell them what games you're hoping to get. If you organize your wishlist well it should be flawless. Then you'll have a pile of gifts to look forward to whenever you get back.

With so many digital stores doing tons of sales, Steam sales are not the unique opportunity it used to be... chances are you can find the game sales you're waiting for anywhere else (check http://isthereanydeal.com/ or similar websites).

According to https://www.paysafecard.com/en-gb/lp-promotions/steam-summersales/
Steam Summer Sale starts on the 19th and ends on the 30th so you should be back before it ends.

Don't worry, our internet in Greece is (still) working. :P

It will start July 11

You are not ready.

19-30 June

steam sales starts on 19.06

you should probably cancel your trip, I mean what's more important than games on sale? :)

Usually the summer/winter sales are 2 weeks, so even if it starts the day you leave it will still be going on when you get back.
OR
I don't see why being in another country would make any difference but you can use a smartphone to buy games, just add some steam wallet funds to your wallet before you leave to make things easier.

I hope you arent from any minority, coz golden dawn is a nasty thing there

oh steam summer sale!!! hold on to your wallet guys this ride can be painful!! hehe
