Darn. Looks like they’ve just changed the deal.
I’d ordered 3 of these @ $11.30 earlier. They had 2 lines under “Special offers and product promotions” on the product page - 1 for 30% and 1 for 15% = 45%. Just before posting here I’d double-check and again was shown the $11.30 - the deal still sits in my Amazon Order Review page and reads
Shipping & handling: $0.00
Promotion Applied: -$6.17
Promotion Applied: -$3.08
Total before tax: $11.30
Estimated tax to be collected: $1.05
Order total: $12.35
When I tried adding the item again just now - alas - I only got the 15% off. This is still a good price for the item, but not as good as before.
Just updated the OP.
