Welcome!
There were some good deals on the James Hobo awhile back, but nothing great right now, unfortunately. The Black is still at Plaza Too for $419.99 (30% off), and it's probably worth looking out for a code, as the price was down to $300+ when Plaza Too had their last code. The Silver is available at
ShopBop for $416.50, but
ShopBop doesn't have any codes right now.
Amazon also has the Silver, at $415.90.
Shopdressonline still has the Black and the Deep Purple, but they're not on sale right now and there are no valid codes at SDO either. (The 30% off tPF code expired on 6/9.) They might mark down their prices again soon, as they usually do have marked-down prices, so it's worth keeping an eye on their site. (Their CS can be a bit patchy, though, so I'd do a bit of research on them in the meantime!)
As for the Nicole tote, I don't think I've seen that around. Hope the info on the James Hobo helps, though!
