For me this is one of those things I assume everyone already knows about, similar to complaints about too many or too long YouTube commercials. Everyone knows about Adblockers and how a mere 32 second web browser install/restart can nix out a lifetime of meaningless commercial watching.
So, how about online buying? How do I know I'm getting the best deal on Amazon.com?
TRUST ME:
It'll take you longer to read this than to get the results you're looking for ALL FOR FREE!
- Go to CamelCamelCamel.com.
- In the search field type in the word "LEGO + SET Number or KEY WORD".
- Hit "Enter/Return".
WHAT'CHA GET:
CCC price tracks ANY ITEM on Amazon.com.
From the lowest price EVER by date.
To the highest EVER by date.
FOR FREE.
Allows you to set in a price alert (free by email) when an item's price falls to an
entered amount, or by an entered percentage off.
Again, ALL FOR FREE.
BOTH YOUR EXAMPLES:

- List of potential items with that name to click further on to see its
price history.

- After you zeroed in on the item you want CCC shows a price history
graph. Gives options to get email alerts when the price hits certain
threshold on either Amazon or 3rd Party sellers.

FINAL SAY:
I don't know why more people aren't using this it's free and it's not really a secret it must the its silly name that throws folks off...
EXTRA CREDIT:
There's another Amazon Price Tracker named KEEPA, but I've never used it.
