If you are contemplating switching suppliers and ordering your e liquids on the Internet, there are some things that are important to check on when considering a new supplier.
A large inventory of flavors -- People get bored with the same flavor of e liquids all the time. If you are using them often, you will usually find you get bored easily as well. This is why you should only ever order from a company that has a large inventory of flavors, so you will never get bored.
A rewards program? -- The best companies selling e liquids online have a customer rewards program. This usually means they offer free e liquids after you have spent a certain amount of money, or bought a specific number of e liquids from that particular company.
Tamper proof bottles -- As your e liquids will be delivered to you through the mail, you will want to be sure they arrive in tamper proof bottles. After all, you never know when the package may be opened while on its way to you, and someone attempt to open the bottles and add something to them.
With tamper proof bottles, however, that will never happen as the seal would be broken and then you would know to report it.
Same day shipping -- Does the company you are going to buy from offer same day shipping? This is important if you are like many people and forget to order your e liquids until you have just about run out.
Free shipping? -- Does the company you are considering offer free shipping above a certain monetary value? Some of the better companies do and, if you can find one, you can save quite a bit of money over a year's time of ordering from them.
