I think that's a question only an individual can answer. Mainly, it's now a savings on insertion and fvf (in some cases)......... but does have some perks.
You have 105 items.......and a store....... Obviously if you have a premium or basic store you aren't using the allotment of "free" listings...... so you are wasting $$....... If you have the "newer" starter store, you have.......
To find the "real cost of a listing", find average the number of sales per month you've made for a couple of months......and then divide the price of the store by that number......that gives you the insertion cost per item, and you should consider that in pricing. If it's higher than 35c, obviously you are paying more than normal rates IF you would sell that much without as many items listed. Of course, that's always the quandary. Would you sell as much?.........
Personally, I'd look for ways to increase sales........and as one who has sold, years ago, items like yours....... a suggestion or two..... Use some dog breed/cat/animal material......... People look for things in those subjects for gifts. I could sell anything with Pugs or Boston Terriers..... Right now ducks and chickens seem to be popular. Sport teams were also good, but since you are mainly selling "woman" stuff, that could be problematic. Themes give you an "in" when people do searches for those particular subjects, even tho they may not be looking at your particular type of item.
With a store (not sure about the starter store) you can also run promos on quantities.......... buy 3, 20% off, type sales to encourage more than one item sales.
just some ideas
