While I agree this would solve the immediate problem in my opinion the problem is deeper than that, you can see how I've proposed to solve this in my thread Upgraded Listing Options: http://dkn255hz262ypmii.onion/index.php?topic=182090.0Quote* Price: The price should be a function where you add ranges of weights and each range gets a specific price. For example product X costs Y BTC for 5 to 25 grams, but if you order 1 to 4 grams you can set it to either a higher fixed price or a higher fixed percentage for each gram, and for more than 25 grams you can do the reverse and give a discount.* Quantity: The same function as always, to list the amount available. The exception now though is that since it's possible to segment different weights into different price classes there won't be any need to create new listings for different weights. This way the vendor can have multiple weight listings yet still accurately able to keep track of the quantity available. Also quantity should work similarly to how Currencies work, ie. you should be able to switch the type of Quantity and also have decimals for products which are dealt in very small quantities, for example mg, ml, pills etc..This would also make it significantly easier to create new Custom Listings. We currently use a system of having a 5 gram listing per product and then five additional price points to a total of six in total. Here's an example of how it looks like in practice, translated from Swedish to English:QuoteThis listing is for five (5) grams for 340,00 kr. Price per Gram: 68,00 krFor a Custom Order contact us. We have the following rates:1-4 grams: Price per Gram + 30 % = 88,40 kr5-15 grams: Price per Gram  0 % = 68,00 kr16-29 grams: Price per Gram - 15 % = 57,80 kr30-49 grams: Price per Gram - 20 % = 54,40 kr50-99 grams: Price per Gram - 25 % = 51,00 kr100-200 grams: Price per Gram - 30 % = 47,60 krI then move the feedback from any Custom Listings to the corresponding listing for 5 grams to a text "feedback" section, not a perfect system but it works quite well for us. :)
