User reviews

Users appreciate Megabonus for reliable cashback storage in US dollars, significant savings, and convenient activation. Cashback confirmation is prompt. However, cashback payouts are delayed, and the extension can be intrusive by opening new tabs. Some sites need manual cashback activation outside the extension. Recent updates raised security concerns among some users.

Pros

Reliable cashback accumulation without expiration, especially useful as cashback is stored in US dollars.
Helps save significant amounts of money (over 150-220 dollars reported by users).
Convenient and easy to use for activating cashback through the extension.
Cashback confirmation messages arrive quickly after making purchases.

Cons

Delayed cashback payout after order receipt, not instantly processed.
Annoying behavior of the extension opening new tabs or 'reminding' users frequently.
Some websites require cashback activation via their own site rather than the extension, limiting full automation.
Concerns about security permissions and data access raised after update.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Megabonus - cash back up to 40% requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
