Variants and stock problem

Hello,

I make candles and give customers a free sample to go with their order. Right now on each product I have a variant for each sample scent people can choose. However, I also only sell in batches at a time, so I may have 5 candles in stock of a particular scent. But, If I set the stock of each variant to 5, my total stock becomes 5xnumber variants, instead of just five in total.

Is there a way to have 5 of one product in stock with the option to pick from, say, 10 addons? (I consider the samples/addons as unlimited stock)

Thank you kindly in advance, Best,

Josephine

So, I found one solution: Adding a custom form field at checkout. Since the sample is free and doesn't affect the price, this could be one way to go.
