So after watching the videos and reading the thread, I think both the buyer and seller made mistakes.
Buyer:
Did not research the seller until after the order was placed.
Should have known on Dec 6th that given the weather forecast at his location (see pic of historical temp data from USClimateData.com), plus the need for people who ship critters to avoid the "Christmas Crush", there was no safe shipping window until at least January. Most sellers stop shipping the week after Thanksgiving because of the increase in shipping traffic plus the number of temp/inexperienced workers hired by FedEx means there's a greater likelihood of a screw-up.
I tried to find similar temperature data for the Urban Gecko's location but could not, the site above is for the US only. I used the data for Buffalo, NY which is right across the lake so they'd be pretty close. Again, unless the shipping occurred on 12/4, it wasn't going to happen safely until January and even then matching up temps in the OP's location, their location, and a Mon-Tue-Wed shipping window there was maybe one chance to get it done for the month.
Seller:
The web site needs to be updated to indicate that they only ship into the US every 2-3 weeks, which is reasonable given they're in Canada. Buyers in the US need to know that.
The web site should have the actual safe shipping temps they use, right now those are missing.
Substituting the second male gecko for the first one that was lost; the buyer should have had the opportunity to pick out a new critter or get a refund since the seller could not ship the specific animal that was purchased.
As for the color differences between the seller's pictures versus the OP's pictures: the two pictures I've attached are a boa I got in 2015. The pictures were taken within minutes of each other by the same camera, lens, etc. Neither has been photoshopped or altered, other than resizing. The difference was in the camera settings. The picture that was more orange/red was taken with the camera's factory settings; my hand isn't really that red! The other picture, which shows the boa's correct colors, was taken after my husband had adjusted some of the settings.
No I don't know what he changed exactly, he's the one with the expensive photography equipment, I just use my phone.
