Amazon tend to be more on the high side as far as kits & supplies goes. Ebay is definitely another place to find great deals.
I've found Amazon with Prime membership (free 2-day shipping) to be about the same or less expensive than eBay plus "slow boat from China" shipping charges. OTOH, if a kit is OOP, chances are MUCH better finding it at eBay.
A while ago I was looking for a 1:24 Mopar 383/440 V-8 to build a more authentic General Lee (which came with the Hemi, which was only used in the movie). I could buy a whole kit from Amazon cheaper than sellers were selling the parts to build the engine on eBay.
It pays to shop around.
I've had to order (Vallejo) paint and detail parts from Sprue Bros. Good service and acceptable pricing. I wouldn't hesitate to buy from them again (and I have).
My LHS is in the business of going out of business. Lease is up and nobody knows if they'll find somewhere else to hang their shingle. That means no restocking, and other customers have picked the place pretty clean. That will leave Michaels and Hobby Lobby as the only local alternative to the internet. Local Michaels has a poor selection. Hobby Lobby is much better, but round trip is an hour plus. Have to weigh time/gas/wear and tear/the unknown of them having what I need in stock vs. having things shipped.
This isn't a small town. By area, Jacksonville Florida is larger than NYC and LA combined. It's the gateway to the rest of Florida, with I-95 running right through it, and the eastern end of I-10. It's just that people would rather watch college football than build models.
Another problem with my LHS, even before this "in the business of going out of business" thing, was that they are more interested in selling $500 R/C planes and even more expensive quad-copters than they are in selling <$100 kits. A $3 bottle of paint? They couldn't care less. "Follow the money." It's tough to be loyal to a business that isn't loyal in return.
