Does Amazon two day shipping really work?

I order something from amazon today and selected the free two day shipping with the trial.
Will it come on Friday since today is Wednesday.
If it does not come on Friday will it come on Saturday?

Check your order online and you should see an 'Estimated Delivery Date', that will be the date on which you will receive your shipment. I have been using amazon for 4 years now and they are very prompt on delivery dates. They have never missed a date for me.

For the most part, it won't ship today. The soonest it will ship is tomorrow. Most retailers don't have the ability (willingness?) to process orders any quicker than that.

I'd love to say that it'll come on Saturday, but that's usually a special request, that comes with an additional fee. It should arrive Monday.

Technically, the answer is, yes, it really works. But this implies that you've read the fine-print, which will clarify that it's two business days after they ship it.

probs not but im not sure .. i did the next day delivery which cost me an extra £9.91 ( i think ) on the top of £90 for my hair straighteners .. i orded these on a friday and they came on the sunday .. so i had to give a full day inbertween .. and i had to pay for it so i dont think it will to be honest :) x
