People dislike Cbid because of the effect it has on their finances and credit balances. Like any auction site it is important to research prices and then set the max you want to bid as a reserve. Never go back and check, that will get you caught up in competitive bidding and going above your max.
Bid low on several lots, winning just a small percentage is a good thing. It means you are spending wisely. Winning a lot is conversely bad. You are paying too much for your purchases. Watch the selling prices on cigars you are interested in purchasing, maybe for a couple of weeks or month. Then you will have a sense of whether the selling price is something you are willing to pay.
Popular, new or "hot" cigars will always sell at a premium, so try to buy "off the curve"
Dont get caught up in the hype, nothing is limited on Cbid. The same lot will be back in the next week or two. Use the search to find your preferred lots.
Finally, set your preferences to ship once a week otherwise you will pay shipping for every winning bid.
