It was partly because of lack of money (end of the month!), partly bad planning and partly bad luck (only green bananas everywhere). Managed to stay lfrv, but not exactly hcrv and promptly felt much worse as a result with next to no energy.
Today was payday, so I could finally order another case of dates. Actually, I ordered two cases, one 3kg case of very cheap, but also not very good non-organic dates because they tend to ship within 24 hours and a second 5kg case of slightly more expensive organic ones which will ship in about a week. Also stacked up on even more bananas and 5kg of mangoes.
My search for bulk buying opportunities continues. One of the two wholesalers I wrote to last weekend got back to me to say that they don't deliver to individuals. I haven't heard from the other one, but that probably means that I can cross them off my list, too. I did find an online fruit and veg shop that sells by the case. They appear to be attached to a wholesaler but I looked through their TOS and found nothing to indicate that orders are restricted to businesses. I might try placing an order in the near future and see what comes of it.
