A few words on the obligations of the Disney Movie Club. While I'm certainly not saying this is ideal (that would be a general release, and there are individual cases where the movie club may not have much to offer), the potential advantage of the movie club lies in the deal you get when you join and average cost. Typically their promotion is 4 DVDs for $1 when you join. In the worst case scenario, here is the math: $19.95 x 5 movies ($99.75) + $3.95 shipping x 5 if separately purchased ($19.75) + 4 $1 DVDs. Divide the total of $123.50 by 9 movies and that rounds to $13.70 per disc (or season set).
If you play it smart, you can do better and save about $3 per DVD. When you join they let you buy two bonus DVDs for $14.95 and $9.95 that count toward that five-DVD requirement, and there's no shipping charge. Shipping charges go down if you buy multiple discs at once also. In the optimal case, the math goes like so: first 4 $1 DVDs + 1 $14.95 DVD + 1 $9.95 DVD = $28.90 when joining. Add that to $19.95 x 3 DVDs ($59.85) + $3.95 shipping for 1 disc and $2.98 shipping for the other two. $95.68 / 9 = $10.63. You'll have saved $27.82 on the DVD membership.
The optimal method is *definitely* what you want to do if you want to have some Blu-ray discs / Blu-ray & DVD combo packs. With Blu-Ray membership everything costs $29.95 (including DVDs...yeah), an extra $10 compared to the DVD plan. If you take the best deal when you join you'll need to buy three movies that way, so instead of $95.68 it should be $125.68 - marginally more than if you were being inefficient with the DVD plan (the average rounds out to $13.96).
The optimal method doesn't get you what I'd call an amazing deal in our world where you can get a DVD for $5 or a Blu-ray for $8 out of a bargain bin, but it could be a "good" deal if you play your cards right and there are gaps in your library that you want to fill. Only you can decide if doing that and having Gargoyles justifies the expense. If you're an avid Disney collector, maybe not.
But that being said, lately Disney has been VERY aggressive about bringing its catalog to Blu-ray. Many more BD releases are coming this year, and we're at the point where by Fall 2014 it's not impossible that every theatrical film Disney has made since The Great
Mouse Detective will be on Blu-ray (at the least I'd bet the farm Aladdin is 2014's Diamond Edition, and it and Tarzan have already seen BD releases in the UK). I would hope most would have good candidates to choose from. Frankly, even if you were to be smacked with a worst-case $39.99 price point on your three extra BD releases with the optimal method, there isn't a circumstance where you're going to break an average charge of 18 bucks - let alone $20. Considering the prices that the likes of the Blu-Ray releases for the likes of Brave and the Peter Pan Diamond Edition typically pre-order for (I don't think I've seen a better deal than $23, and that's at best), in the big picture the movie club actually can amount to a good deal.
Personally, that kind of money for Disney Blu-rays + approx 600 minutes of Gargoyles is something I can live with.
