Any time anyone prepares for a hurricane its a good thing, regardless of whether the storm is approaching or the start of the hurricane season. Besides we do not know the financial situation of the people buying "last minute". Some people are poorer than others, and have to delay getting their hurricane supplies until they think they absolutely need it. The good news is, as it appears they are close to you, is that they will now have their supplies for the rest of the season. Also they could be shopping for others that are in the cross hairs of the storm. Keep in mind everyone's situation maybe different. I am more more fortunate than others, but I try to keep that in mind when facing the last minute hurricane crowds.
