Add ability to track if a discount was applied, how much, and if there was free shipping

[EfficiencyJunky]

To do this we need to make the following modifications

GOOGLE ANALYTICS CUSTOM DIMENSIONS / METRICS
Dimensions:

• Order Discount Status
• Free Shipping

Metrics:

• Order Discount Amount

MODIFY CODE IN: 01_ss_rawTransactionPush.html
Needs to push this object to dataLayer

discount = {
	'status': (discountAmount < 0) ? "Discount Applied" : "No Discount",
	'amount': (discountAmount < 0) ? discountAmount / 100 : 0,
	'freeShipping': (shippingTotal == 0) ? "Yes" : "No"
}

GTM DL VARIABLES
DL - EEC Purchase - Discount Status -> discount.status
DL - EEC Purchase - Discount Amount -> discount.amount
DL - EEC Purchase - Free Shipping -> discount.freeShipping

TAG MODIFICATION
Add Custom Dimensions / Metric to Purchase tag

• Custom Dimensions:
  • Index 4 - Dimension Value: {{DL - EEC Purchase - SS Transaction ID}}
  • Index 8 - Dimension Value: {{DL - EEC Purchase - Discount Status}}
  • Index 9 - Dimension Value: {{DL - EEC Purchase - Free Shipping}}
