99.9% of the time you dont have to use the visa card. i've tried cash, AMEX, and even merchandise credit. fyi the one time i did need to use it was when a manager came over so have a visa card handy.
Limits:
1 coupon per email address( cough cough use LINKY to get temporary email address cough cough)(or use the gmail '+' trick (ie john@gmail = john+lowescoupon01@gmail.com)
2 coupon per REAL mailing address (change the number of your street)
10 per IP (public library computers all count as 1 ip address(from what i seen))
Note: if you're going to use multiple on the same trip DONT go to the same person to check out. 70% of the time they dont care(this means they dont even read it), but today one of the cashiers did notice 
this coupon can only be used when u have $25.00 of stuff BEFORE tax. if the cashier scans it when you dont have that much, the coupon will be INVALID
idiots guide to getting a lot of these coupons:
1. fill in any name, your neighbors address(or find a address thats easy to type like 1 first st)
2. use LINKY to generate your temporary address.
3. press submit and wait(takes 10-60 secs to get to mailbox)
4. after you received your link print it or copy it somewhere(ie word doc)
5. clear your cookies (i find that using something other than IE makes this step really easy)
6. repeat with a different temp email
7. after 2 change the street number
8. after 10(it will say you have printed the max for this ip) find another internet source (i used the different public library's in my areas and the free wifi spots)
