I confused myself. Here's the final analysis:
| Costco MV | Costco online | Amazon | |
|---|---|---|---|
| Std Digital Rebel with EF-S 18-55mm f/3.5-5.6 lens package | 949.00 | 949.00 | 899.94 |
| Extra battery pack BP511 | included | included | 69.99** |
| Carrying case | included | 59.94 | 59.94 |
| Shipping and handling | included | included | included |
| Tax (CA) | 80.67 | n/a | n/a |
| Rebate | -50.00* | -100.00 | -100.00 |
| Total | 979.67 | 908.94 | 929.87 |
*You can probably use the online rebate form to claim the $100 for the in store purchase, but I'm not absolutely sure.
**Many generics are available for substantially less - more like $20-30.
i shoot with a canon 10D and i've bought batteries from:
http://www.sterlingtek.com/ln03-canon-bp-511-dlc511.html
very reliable batteries at $12 a pop. they've worked great for me, as advertised without fail. grab 3 or 4, it's worth it.
