Im purchasing an iphone case on amazon. The one im buying cost 8.49 via amazon plus tax but i see that the seller is a certain person that also sells it on ebay. I also have some 3 dollar and so change on gift card so when i purchase it, i could get it for bit more than 10 dollars due to shipping. It says delivery estimate is march 7. However... i saw i could buy the same item for 5.50+2.99 shipping and thus its same 8.49 price. Differene however is they say shipping estimate would be march 10-13. This is the same seller on ebay. So if i buy it from seller and shipped from seller, its about 5-6 dollars less. But isn't buying it from amazon going to come from the exact seller as well? $8.49 + 5 to 6 dollar tax http://www.amazon.com/Caseology-Apple-iPhone-Saffiano-Hybrid/dp/B00AGOK0OQ/ref=sr_1_4?s=wireless $5.52+ $2.99 tax http://www.amazon.com/gp/product/B00A70MP88/ref=gno_cart_title_1?ie=UTF8 Can someone explain this? So if i buy it 5.52 plus tax so 8.49 total and thus 5-6 dollars less, im going to get the item few days later? It does say estimated shipping is march 5 or march 6 though. For the amazon one it say estimated delivery is march 7. Im confused because dont both come from the actual seller? I did read if you buy it directly from amazon, amazon ships it directly so you would get it faster than from the seller? Because if they both come at same date, obviously i would choose the lower price b/c its the same case.
