Mileysmommy…I bought the Answer OPK one-step package and the Answer OPK lab strips this month…I actually had more luck with the lab strips and they were cheaper than the one step sticks. I got the lab strips at Frys, and they came 20 strips in the package for 19.99…but I opened it and just pulled out the 2.00 off coupon at the register and they were under 20.00 bucks after all was said and done. It’s just about comparable to the internet cheapies, and you don’t have to wait for them. The one step package I got at Walmart for I think 8.00 or so? It came with 7 sticks and I used those along with the strips, but with the sticks, I always had two lines and had to speculate on the color darkness and whether or not it was pos…with the lab strips, I didn’t get two lines until I was getting my surge…took a lot of the guess work out of testing (for me anyway). I hope that helps!
