Crazy8.com is holding a Crazy Cash earnings event right now through April 3, 2011. During this time period, for each $40 amount you spend in a single transaction at Crazy8.com or at a Crazy8 store, you will earn $20 in Crazy Cash to be spent on purchases of $40 or more between April 7 and April 17, 2011. More details are listed here.
Plus through March 27, you can save 25% off your entire purchase with this printable coupon or when you enter code C8BUDDY at checkout. However, in order to earn Crazy Cash, you will need to spend $40 after any coupons and before tax, shipping fees, etc.
Crazy Cash can also be earned in Crazy8 stores.
I spotted several shirts starting at $4.99, so with the additional discounts, you should be able to score some good deals!
