What to buy in the States?

My husband and I are heading to Vegas in August. Any recommendations for items to purchase while I'm there that we can't get here? Cheers! 

Great question!!

The search button feature has some great lists.  For me I make my own soap so buy lye and other soap making supplies I also love to go to savers which is the same as value village but much cheaper.  They have a good selection of vitamins as well as sugar free item.  Swiss miss makes a good diet hot chocolate that is as good as the home made stuff I created last christmas. I've read people buying cake mixes to noodles ?. I have not had either as I'm not that far out I bought the sugar free ketchup but I do not eat anything that I would eat it with..... So when shopping go slow because you may not like it after or even use it three bottles of sugar free ketchup.  I also bought jam but again will not eat it.  I love there greek o Fage yogurt.  And I bought the small calcium tablets and lots of those but have not been able to stop taking the wellesse liquid.  I guess I'm saying I spent two years shopping in advance and wasted money so have fun and shop wisely.

I just did a quick cross border trip for sugar-free products not available in Canada (or at least Ottawa).  I bought lots of Jello brand puddings and gelatine that are sugar-free and fat free such as cheesecake, banana pudding, and strawberry banana jello.  I also bought some sugar-free low carb high protein Greek frozen yogurt but don't imagine you want to bring that on the plane;-) I find the selection of sugar-free candy and sweets better in the US.
