Using Swagbucks versus ebates canada for shopping [help needed]

[zealot1205]

Hi , I need an honest opinion/ advise on buying these 3 deals :
1 from groupon for a hair cut local , there is a special 20% off anything offer on groupon personalised for me ri8 now
1 from amazon.ca for kitchen scale is on sale for 22.97
1 from walmart canada , ironing press is available for $54- $70 range

here are the cashback/ rewards
through ebates canada : Groupon 3%, Walmart 4% and amazon 5 %
through Swagbucks : Groupon 3 SB/ dollar spent , Walmart 4SB/ dollar spent , Amazon canada 1 SB/ dollar spent

How do i maximize my returns on the purchase of these three deals from these 3 sites ?

I know this is a math problem which i can solve but the reward types are different, SB pays in accumulation of points i jave 25 SB as of today
because i just cashed out 450 SB for $5 amazon card yeterday
and on Ebates iam currently sitting at 11.97 dollars in account

Help please !!!

please move to appropriate thread group if it doesnt not belong here

thanks lecale, i checked the amazon store on airmiles.ca , the only special promo they have is 3 X airmiles. [no greater than 10 multiples] :-(
also i was thinking if i wait for the Swagbucks amazon e-gift certificate to arrive , i could reduce my total oop in the first place to buy the kitchen scale wouldnt i ? I will then use airmiles . Quick question does the airmiles apply only towards the amount you pay from credit card or does it also apply on the payments made through e-gift certificates in amazon ?
