hi hun. i bulk buy on eBay, i get tests for around 20 cents each from Fertility2Friend . i can't say if they're good or not, as i haven't had a BFP with those. my first BFP (which resulted in a m/c) was taken with a FRER, and didn't have any internet cheapies to compare. but the OPKs from Fertility2Friend work great! sorry i wasn't much help.. lol
