wow thank you for this...I say its def worth the money, but I may wait for a sale, lol
Try buying from ebay ...that's where I get mine ...I get a pack of 10 for like 16 the most ...another thing make sure u get 2017 or later expiration date..
Also if u see some that will expire in 2016 an u will be testing within the expiration time frame ..it's even best to get those ones as they will be much cheaper... an u will use them b4 the expiration date...
Loads of ppl use them after the expiration date including me and they work just fine...it's did my own experiment with one that still had shelf life and one that was 4 months pass the expiration date and they both have me my smiley face...if u don't trust my info u can research using them after the date n see what others say or just don't buy close to the expiration date if this bothers u
But thats my trick to having them cheap
Hope this helps
