How should I be expecting iPhone 5s shipping time to change?

I would like to buy the iPhone 5s before next Monday, because that's when I'm leaving the States; I would prefer to buy in the States because it's significantly cheaper than in my country. However I don't see any indication that the shipping time will decrease or that Apple Stores are going to receive any stock…
I want to ask how exaclty does shipping time change… I mean is it possible that it goes down to 2-3 days from 2-3 weeks (at the moment)?
Also, is it possible that some stores still have stock? And finally, can you recommend any alternative for buying an iPhone 5s that would be possible at the moment? I need the T-Mobile $749 one…
Thank you very much, I really hope I figure out a way to get one, I'm obviously desperate

T mobile should have them in stock. The carriers here all have them.

Btw, the total cost of apple products do not change apple forbids it and anyone caught selling it at a reduced price will have their ability to sell apple products taken away by apple. The most they can do is give a discounted upfront cost with a contract and prorate the balance over the contract period.

Apple does that so people don't go to other countries to buy and to keep their prices and reputation up.

Iphone 5s is in high demand but low in stock… But it is possible that some stores or carriers might have it in stock. But please be aware that if you buy your iphone overseas and take it back to your hometown country or wherever your living, the warranty doesn't apply to that country. The warranty is only valid in the country of purchase. So for example if you buy the iphone in the States and took it back to your country and for some reason it stopped working, you would have to go back to the states, or post it to someone in the states, to get it fixed. So yes keep that in mind, it might b worth paying a little more in your hometown just in case your phone stopped working somehow and you need the warranty. I learnt it the hard way.
