A Little Bit of Crypto - I have been trying to figure out to "collision resistant" some of these standard hash functions are. It is a tough concept to get my head around. I figure...
Tonight I was doing some shopping online. I went to Kohl's. Found I could use my $10 off coupon online. Cool. They had some furniture I needed. They also offered free shipping since my order was over $75. Things were looking up. Then on the payment page I saw that I could use up to two coupons. What? I don't want to leave any money on the table.
Spent ten minutes googling around to find a 20% off coupon that I applied. Nice. Now that I was spending at least $100, I was also expecting two $10 Kohl's cash coupons back. I was just over $100 with my taxes. I could not find details anywhere to see whether the Kohl's cash was awarded on merchandise only, or whether it included tax.
Turns out the Kohl's cash must not count the tax. Ouch. I just lost one $10 Kohl's cash oppotunity. Well we shall see how Kohl's online does for me. If the experience is good, I might just redeem the Kohl's cash and make more purchases. This experience has taught me a lesson. New merchants must navigate many chances to turn off new customers. Kohl's almost failed. Let's see if they recover.
My hosting company gave me a coupon to use. If I spent $25 on AdWords in a month, they will give me $100 of free advertising. Not sure if this is a global campaign bonus, or just an incentive for some type of local AdWords deal. I need to attract global customers.
Hey. I guess it is worth a try. However I figure it will take more than $25 or $100 to figure out how to use AdWords effectively. But I got to start somewhere. Why not start with AdWords?
