I have used both for years and honestly, CamelCamelCamel is much better for simple alerts when you are on a tight budget. Keepa has way more data, but if those graphs confuse you, its just gonna be frustrating. Here is what I found works well:

• CamelCamelCamel is way cleaner for just setting a price and waiting.
• Keepa shows more detailed stuff like shipping costs and warehouse deals, but its overkill for most.
• Both show the same basic price history, so you arent missing out on the core data. Since your budget is tight at $300, Id suggest checking out PriceDropCatch too for quick alerts. I am really satisfied with how much I have saved on gifts by just setting these up and ignoring them until the email hits. It makes the whole wedding gift hunt way less stressful.

Like someone mentioned, Camel is simpler, but I disagree for a $300 purchase. In my experience, Keepa is technically superior because it tracks the Buy Box price. Camel often misses third-party shifts that save you money.

• Keepa monitors stock levels.
• It tracks lightning deals.
• The data is more granular. If you want the best deal by July, learning the Keepa graph is the better move. Its worth it.
