Buy the batteries and stereo online:

4.99*2 = $9.98 + $90 = $99.98

6.99-5.00 = $1.99

99.98+1.99=$101.97

3Cds in store

7.97*3 = $23.85

5% tax = 1.19

10% off = 2.39

$23.85 - $1.19 = $22.66

22.66 + 101.97 = $124.63

All in store:

12+100+23.85 = 135.85 - 6.45 = $129.40

All online:

9.98 + 90 + 26.85 = 126.85 + $1.99 = 128.84

Physical store: 15% discount; 6% sales tax.

Online store: $5 off; shipping fee $8.99

Let us assume that the total item bought costs $100

Physical store:

100 x 15% = 15 discount

100 - 15 = 85 discounted cost of item

85 * 6% = 5.1 sales tax

85 + 5.1 = 90.10 total cost

Online store:

100 - 5 = 95 discounted cost of item

95 + 8.99 = 103.99 total cost

It's cheaper to go and visit the physical store.
