Welcome to the forum!
DO NOT and I repeat DO NOT but ANY so called paracord from the stores you mentioned.
That is not real paracord that those stores sell.
You can however if you are just looking for a small amount to try and test is go to a craft supply store Michael's and Johann's and buy some.
The paracord you saw online was rated at 750lb that is Military spec paracord. It should have 11 inner strands with one of those inner strands being a different color than the rest. (The color depends on the manufacturer of the paracord)
Now if it doesn't say in the description of having 11 inner strands than it it just either a typo or the seller is mistaken between 550lb and 750lb. The difference being 550lb has 7 inner strands and 750lb has 11 inner strands.
So read the description again and see if they mention the count of the inner strands.
550 paracord is often called Commerical Type III.
750 paracord is often called Mil Spec Type IIII.
I was able to get my hands on a total of 50 feet of 750 paracord and you can easily tell the difference between 550 Commerical and 750 Military.
