As someone who has used both over the years and continue to do so what a load of BS.

over the last year I have used shopback more than CR. Flip was significant for me in terms of benefits.

Cashrewards have their fair share of lost tracking. That is what support is for.

Shopback is much more polished in terms of app features and has better advanced instant tracking
As far as being much for the muchness that is true. However big promo deals can be significant. Like spend $10 and get $10. Also there can be different shops in one or the other

if you are smart you wouldn't choose one or the other you would have both.

ozbargin deals generally list the different cashbacks
