From the research I did, to be totally sure you will be covered by warranty, you have to buy from “Authorized Resellers” on ebay. They must specify that the warranty is included. So I went to Ebay and found authorized retailers, and looked at the kits they have for sale. Boy, you really have to watch out! They will picture a Lexar SD card in the product picture, then sell you a “General Brand” SD card. But I went through all the kits, and found the best ones, and narrowed it to 2 options. If you want just the 18-135 IS STM, it’s $1349 here. For ~$150 more you get the excellent Canon 55-250mm included for $1489 here. You will NEVER find a good tripod in a bundle like that. I think that unless you are willing to buy used or refurbished, you’re not likely to find a much better price than this unless there is a special sale. The good thing about these kits is, they leave out all the junk! You’re not getting anything you won’t use!
One thing to remember is: with the more expensive kit that I linked to above, you’re not only getting the 55-250 but a battery charger, UV filters, SD card reader and a useless little table tripod. The other kit doesn’t include those items.
Also, you can buy the 70D with an 18-55 IS STM kit lens for only $1,149 if you so prefer. It’s up to you!
Another thing to keep in mind is… B&H has a NICE bundle for $1359.00 which also gives you substantial discounts on Adobe Lightroom and other items.
